Skill-based matchmaking might be a part of Apex Legends for a while after a response from a Respawn dev suggests the online feature is here to stay.

A portion of the Apex Legends community is still reeling from the effects of SBMM since it pairs people in all playlists with other players of similar ability.

While more skilled players want it removed to destroy noobs for highlight clips and content, others look for a casual setting to play with friends of varying skill levels.

A response from Respawn Entertainment Principal Coder Michael Kalas was essentially the nail in the coffin for people wondering if Apex would ever scale down the matchmaking feature.

A player chimed in to ask if “random matchmaking in the ‘Play Apex’ mode” could become more prevalent instead of the effects from SBMM that makes every game, Ranked or not, filled with competitive players.

The developer simply replied with a gif of Dave Bautista with the iconic ‘Deal with it’ sunglasses superimposed on him. While it was a brief response, it echoes what the Apex community have been hearing about SBMM from the devs.

Even in the Season 4 patch notes for the game, Respawn gave a ‘Matchmaking Update’ to the community. In it, the devs doubled down on their decision to include SBMM saying that it “has existed in Apex since launch and [they’ll] be continuing to improve on it over time.”

In that update, they acknowledged that SBMM has been a “contentious topic among players” but maintained their position that it’s going to stay while they look for natural improvements to make.

Previously, Respawn Senior Systems Designer Eric ‘Ghost’ Hewitt told their players that SBMM “will become the norm for most MP games,” citing the “indisputable evidence” that “it helps out something like 80-90% of the community with retention for most of those games.”

Ghost’s comment on November 24 and the February’s Season 4 patch notes both suggest that SBMM or its residual effects still need some refining.

The decvs will continue honing their online matchmaking system to appease their players, as much as they might want SBMM taken out of Apex Legends.

Apex Legends SBMM controversy: Is EA rigging your matches?

In the midst of Season 6 in Apex Legends, the controversy about SBMM (skill-based matchmaking) has reared its head again. A 2017 paper from EA researches appears to show a nefarious matchmaking algorithm, leaving players both concerned and angry.

But, before you grab your pitchforks, there are a few key facts that have been lost among the debate on social media.

In an attempt to better explain what we know about matchmaking in Apex, the research from EA, and what it all actually means for you – the player – here is everything you need to know.

First, though, if you don’t know what SBMM even is, here is a quick recap.

What is SBMM?

Skill-based matchmaking is the name for the predominant system used (or allegedly used) in the majority of online, PvP, multiplayer games. Respawn, the developers of Apex Legends, have confirmed that their system uses skill level as a factor in matchmaking.

They’ve said that this system has always been there, will stay, and that they are constantly trying to improve it. The say SBMM is better for the long-term health of the game, and for keeping players playing and having fun.

However, this 2017 paper, written by a handful of researchers from EA, appears to argue the opposite; that fairer matches are not actually best for ‘engagement’ (i.e. keeping you playing or spending). Instead, another system called EOMM is apparently better. So, is SBMM not actually a thing at all?

SBMM has been a hot topic in Apex for ever since launch.

Is Apex Legends rigging you to lose?

The short answer: No.

Respawn’s Principal Coder Michael Kalas has confirmed that Apex Legends does not use EOMM, and said “no one working on Apex matchmaking has read the patent.”

“Apex matchmaking is designed off skill. It’s not literally designed to make you lose, spend, nor play longer,” Kalas confirms. “Apex features are designed and measured to result in fun, entertainment, accomplishment, playing longer, etc.”

Some players, even professional players, have said based on their own feeling and experience, that there is some kind of system working against them in matchmaking.

Perhaps players are right to feel this way, perhaps not. We will probably never know for certain, as publishers like EA and Activision will never reveal the inner-workings of their matchmaking algorithms. This is because, once known, players could deliberately attempt to game the system.

What is the EA research paper?

First, remember that this 2017 research paper is not linked to Apex Legends. After all, Apex was released two years after this paper was published.

It is simply a study, testing if such a system is successful at increasing player retention, and in turn, spending. This system is not SBMM. In fact, it argues that SBMM is actually worse for increasing player retention.

The system is called EOMM = engagement optimized matchmaking. Rather than matching players randomly, or based on their skill level, it combines a number of different factors, to try to increase ‘engagement.’

The paper concludes that “EOMM significantly outperforms all other methods in the number of retained players.”

What is EOMM?

Engagement Optimized matchmaking (EOMM) “aims to match players in an optimal way that maximizes overall player engagement.”

Based on a player’s last 3 outcomes (W)in, (L)ose, or (D)raw, the risk of them quitting changes. The paper presents this table, showing that three losses in a row, or two wins and a loss, will result in the highest risk of quitting (4.9% – 5.1%).

However, if a player has DLW, LLW, LDW, or DDD, their risk of quitting is almost half (2.6% – 2.7%).

A simplistic appraisal of this system then, would be, if you get a win, you might get a harder opponent the next match. If you lose, you get an easier opponent. Keeping the balance of wins, losses, and draws, is core to the EOMM system.

The fear is that the game could be “rigging” your matchmaking, to make you win or lose in a certain pattern. The goal of this system is to increase player engagement; things “such as time or money spent in the game, the number of matches played within a time window, or churn risk.”

But, the research paper was based on 1v1 matches, which might apply to a game like FIFA, but not Apex Legends. However, it concludes that EOMM could easily be applied to other, more complex matchmaking.

Games like FIFA could use EOMM, because it’s based on 1v1 matches.

Of course, EA and Respawn want players to be engaged with their game. They want players playing, staying to play more, and hopefully, spending money. So, it stands to reason that they would employ some matchmaking algorithms to optimize this.

But, this study was based on 500 players. Not the tens of millions who play Apex Legends. In the real world, there are countless other factors to consider, including ping, server location, partying up with friends, and much more.

What about SBMM?

The paper on EOMM argues that SBMM doesn’t work because of one key reason:

“Consider a cautious player who cares about protecting his rank among friends, and a risk taker who enjoys difficult matches. Pairing them with similarly skilled opponents will affect these players very differently. Even for the same player, their expectation on the coming match when they just lost three games in a row can be very different from that when they recently performed well.”

In their testing, EOMM retained 0.7% more players compared to SBMM, after one round of matchmaking. This might not seem like much, but over more matches, this number will increase: “For players who play 20 rounds of matchmaking games within eight hours, there will be 15% more players retained by EOMM” than SBMM.

But, the dislike of any system that is not purely random and based totally on connection, cannot be denied. It became a massive issue during Call of Duty’s Black Ops Cold War Alpha recently, where even pro player Scump pleaded with developers to make changes.

We can only hope that the developers take into consideration players’ concerns, and promote having fun in the game, and not just “engagement.”
