3v3 Matchmaking Is Somehow Even More Broken

So I have 3 accounts. My main account that I have well over 1,500 hours on has a GM3 peak in s3 or something, I always play with my 2 buddies or at least one of them. Since that GM3 peak it is completely impossible to get out of plat-mid diamond somehow to this day while playing in a 3 stack.

Around s3.5 I swore some shit was going on and it was not myself nor my buddies fault we were HARDSTUCK on those accounts. So I made a new account that I only play with 1 of them at a time. Since then we have been able to WALK up to C1-Eternity every season, I also broke T500 twice.

My third account is a solo account that I have only played on for 2.5 seasons but in those seasons I was able to easily solo up to C3--2.

This entire S6 we have been killing ourselves trying to get out of plat 1 LMFAO, the team balancing in 3s is so unbelievably broken its insane. Every, single, game, we get instalock SG, Wanda, Adam, Widow ect. Meanwhile the other team is running dam near perfect comp every match. Even if I get lucky enough to lock Hela or any other of my mains (I flex) and get 25+ finals consistently, its not enough to win lmfao. 3 Stack matchmaking is broken.
