Ranged Mages in ARAM are still op.
Even though the new changes are targeted to get rid of overpowered mages in aram, they are still dominating and better than melee champions. Even though we can ban 10 champions, it still isnt enough to ban every single mage in the game. Banning champions doesnt solve the issue because there's always another mage you cant ban that will be in the game. Even with nerf to their stats as well, the design of their kits will always be better in aram compared to melees.
Aram still doesn't feel diverse. Players will just incentivize to play ranged champions instead of melee. The fact that you can reroll for a better champion that could be ranged and the fact that the champion pool isnt opened completely is the reason why aram isnt truly random. There will still be players using aram accounts that have op champs and we will always see mages in every single game while players ignore playing weak melees like udyr and kha zix. I've played aram for months experimenting to never use mages and I can confirm that the game will always feel unfun if you never play as a ranged champion. There isn't a single game that a melee champion always has an upperhand in the game because ranged champions are just too good in aram. If we can make the game better, we would have to make players play more melees instead of focusing on getting ranged champs.
