ARAM Forced 50% win rate is real
I have 2,194 wins, and 2,194 losses on my main ARAM account. I don't play with 5 man premade so dont bother flexing... after winning 10 in a row, I got 10 losses in a row. This is absolutely forced to be 50/50. The auto loss liability players are systematically assigned and it is blatantly obvious when Riot wants to negate a win streak.
Also ARAM is srs so stfu
