I don't understand why people hate on new icons so much. I think it's a "changed it so it sucks" mentality. While some of them do seem a bit weird at first, it's probably just because they stand out so much (on a small note, why they changed the icon for Ruby Crystal but not Sapphire Crystal is beyond me). The items in particular are much less cartoon-y now while they match their namesake much better.
Only thing I don't recognise from the game out of these is the Tryndamere one. Is he getting new ability icons or something? He definitely needs them imo.
