I feel ARAM tends to naturally warp some champions, due to it being basically just one mid lane, rather than a full map with a jungle and side lanes and everything, so a great deal many champions just naturally don't do well in that scenario. Unlike a spell like Mark/Dash, though, the ARAM aura is auto-applied and not optional, so if there's a class of champions that doesn't do well, then the aura could be adjusted to give them generic, and perhaps more drastic buffs (e.g. much more base movement speed to melee champions, for example). However, you're right that this wouldn't solve all of the issues with those champions, and as much as I personally dislike map-specific balancing, it would likely have to be heavily applied for those champions to not feel like auto-lose champions.
