I really dislike some of the Queue/Champ Select/etc changes. I feel like it takes so much longer for a game to get started now than it did before, honestly? I mean, it LOOKS nice, but functionally it needs some tweaking before it's really... great.
As far as Champions, yeah a few of them have kinda gotten out of control and need to be worked on asap pls rito. Permaban the Soraka for days.
