Honestly the biggest issue with ARAM is the dodging.

After dozens of games this is imo the biggest issue with ARAM, even more of a problem than ARAM smurfs. Not only does it make queuing take 5x as long as it should, it's just extremely negative all around. Enemies that dodge get punished, but they avoided using a bad champion or having a bad team comp. This means that the players who don't dodge are statistically inclined to having more bad games.

After several losses where I felt helpless as a worthless champion such as Yasuo, I finally end up with Ziggs. Someone dodges. Oh cool now I have Lux. Someone dodges. Finally the game that nobody dodges the enemy team has Lux and Ziggs and I have Yasuo. It's such an awful feeling because you're punished by leavebuster if you dodge, and you're punished by losing if you don't. This shouldn't be a decision you have to make.

I think the punishment for dodging should be far more severe in Aram or force you to play the champion you rolled before dodging, if it's not actually going to be ALL RANDOM.
