too much RNG
it's a really neat game mode... I like that the games are shorter, and the gameplay is more relaxing..
However, it's just TOO much RNG.
Most of the time when I win or lose, I don't feel strongly that it was because of choices I made. Of course one can make horrible choices that will ensure loss... but when I build up a bankroll and bench and still the random item and champion drops are totally not what I need it sucks.. Even worse, when I get exactly what I need, I don't feel it was anything I did. It was just luck.
The game mode seems to have a semi-addictive quality.. so I think it'll be popular... but I won't be playing it. I'm not a gambler. I'm more of a strategy game player (chess, go, SC2, league)
