Thoughts on ARAM Balance
So, the new items definitely can help, but I just played a game that pretty much opened my eyes to the main reason why poke comps are so devastating in ARAM, and it's not something that can be fixed with itemization.
Thing is, if the enemy team has 3 marksmen and 2 supports, you aren't going to win even if you have tanks, skirmishers, carries and mages. A balanced team cannot hope to fight against a ranged team, because ranged teams are just better at sieging. The game is split between team fighting and sieging, but when sieging is just how you win the game, then the team that is better at sieging will win.
So, ARAM balance team, I have a pretty simple solution for this problem. Remove the turrets from ARAM entirely. Remove the Nexus, remove the inhibitors. Just have the minions spawn, with no supers, and let us fight. ARAM is supposed to be a bloody free-for-all deathmatch, but when you manage to pick up three kills and you still can't get anywhere because your entire team is melee and you get poked off the turret, then it's not fun.
The existence of turrets as an objective in ARAM will ALWAYS favor ranged champions, period. There's a reason the carry is mandatory on SR, and it's not fun when you aren't guaranteed to have one on ARAM. Just remove turrets. Just make the game an honest deathmatch to 50 kills. That would be so much more fun, satisfying, and so much less stressful.
