Re: Why SBMM ''cuts out the middle man''
This may not be SBMM's wrong doing. The queue needs to constantly have 60 20 bomb / 4k / Apex Predators to open a match just for them and keep them out of other lobbies. If we consider that they are like 0.2%, this would roughly translate to having a queue of 30.000 players on every server, at any time, which is pretty impossible.
Also, considering the limitations provided by queue numbers and premade party combinations, the formula becomes pretty irrelevant. Anyway, I suspect it's something really basic, like kills/ hour, maybe coupled with a few conditions like a minimum damage done, time survived, placement , xp acquired, etc..
