This game is broken on several levels.
Lots of ADCs are super strong and OP. Mages have been rendered near useless in midlane. Summoner's Rift has turned into Dominion and ARAM, i.e. one team, hell one CHAMP gets a lead, the whole thing snowballs and the game is over. Also, if you don't know, whatever happens in SR transfers over to the other modes so Dominion is now even worse than before (FIX THIS MODE RIOT AND STOP DRAGGING YOUR FEET ON IT) and ARAM also has games snowball harder and faster. Turrets are a joke, you literally cannot count on their protection AT ALL now. Champions can just walk past them even with no minion wave push and nothing will happen to them, and you're fucked. FIX THE TURRETS NOW RIOT, GIVE THEM BACK THEIR HEALTH, GIVE THEM MORE DAMAGE AND FIX THE DAMN TARGETING SYSTEM ON THEM ALREADY WHICH IS THEIR BIGGEST PROBLEM!!
Me and my friend play this game on Normals so we can have fun while still being competitive. Now we can't have fun unless we're stomping, because it's either you stomp or get stomped. Meaningful, fun strategic matches are dead now. We are both thinking of quitting the game because it's just not fun anymore. Yes, last pre-season was pretty bad intially with the jungle changes. It wasn't THIS BAD. I used to feel like I could come back and still have a decent game if I fed a few kills. Now if I feed only 2-3 times, it seems like now it's like I just lost the game for my team. It started to feel that way before, when Vayne became OP and the Juggernaut re-works happened, but now it's much worse.
Riot, you may not do this, but you should seriously consider doing it:revert everything back to the tank meta. Stop doing this constant change of it. The meta was fine, it just needed some smoothing out and it would've been close to perfect. Why are you so gung-ho about this notion of keeping things fresh by changing everything, especially when it pretty damn good the way it was? Stop designing this game around pleasing the LCS players and their crowd. Focus on US, WE are your core audience and when we go, you won't have much left.
