I've been playing tons of all random all bottom in dominion lately, and honestly the gamemode is great. Lots of fastpaced action, and even if you lose comeback is usually possible plus the game is short which lessens the frustration of losing.
But one thing that I've noticed is that 50% games are cancelled at champselect due to dodgers.
I mean really, you are joining a game of RANDOM. Why the hell leave? The mode is not serious, why be so tryhard? If you get 5 ad, suck it up, those are the rules of the game. It rarely happens anyway.
Please, when you join an AR game, suck it up regardless of the teamcomp. You're here to have fun, if you're that desperate to win go play ranked..
That is all..
