Power creep
I'm starting to see multiple tank teams again that are unstoppable, i've faced the same comp about 10 times now in the past 30 games, alistar, malphite, sion, and basically the CC, engage, damage and sustain are way too high, the ONLY people that can do anything to them are ADCs with high crit and last whisper, mages don't do anything to them, they don't have a statikk shiv or phantom dancer equivalent, and void staff just doesn't give the same feel as last whisper IMO
The damage dealers have been nerfed too much and sion/alistar's tankiness is way over tuned...i want to add Leona to the list but she's actually not quite as bad...I really don't want season 2/3 back, if you're going to nerf everyone's damage please at least offer items that increase the damage again so that a choice has to be made to be high damage glass cannon and that that is actually an option, because right now i'm getting sick of playing the game having to run a bunch of tanks and have a limp noodle fight for 6 minutes before someone finally dies
