SBMM works for anyone, doesn't have to be a top tier player. For example, you might be in the top 50% but you still might get matched against someone from another continent because they are "equal skill" to you. But the higher you are, the more laggy connections are for everyone in that match. This system IMO is flawed because first of all we don't have dedicated servers. And no ranked and casual playlist. Not every top player like sweating their ass off to win a game just for fun. If you use a gun to try it out then RIP. If you play with a friend who isn't as good as you the RIP. If I want to do sweats, then I will organize scrims to play with top tier player. If I want to have fun then I go into regular PvP which I can't do anymore either because everyone who is equal skill to me is trying win so they have to try hard and give full attention. TL;DR - SBMM works for everyone so you could still have atrocious matches even in TOP 50% - Not every player is looking sweat and give full attention to have fun but still hope to win the game. -Read the paragraph
