Nobody seems to have addressed the real Meta were in.
sure it might be the assassin meta, or the tank meta or the adc meta. when that many things are viable i dont think its any one meta, however i have noticed a pattern. Unless you stomp the enemy team and end the game by 20 minutes the enemy team wins with a comeback. I think in my last 10 games 6 or 7 of them have been loses because despite being heavily in the lead for the first 30 minutes the enemy eventually comeback and win. I dont know why but this has been a trend (at least in my games). probably because im just shit.
