keystones totally ruin this game
The diversity in them is terrible, only ranged adc and yasuo/tryn really see any benefit. For example, i play full ad nocturne mid and it was amazing last season but now its trash because there's no viable keystone as you don't build crit and you don't have time to auto 10 times. Also, nocturne in lane along with some other champions needed mana pots just to function and was left out of the "compensation" changes wtf
