Right now the only classes that aren't rheeling from recent changes are fighters/bruisers/assassins/juggernauts (AD ofc). I think introducing changes to improve fighters/bruisers right now would be a stupid idea as they are currently taking over midlane and bot lane. It's not that other champions/lanes are more important, it's just that riot have spent half the season screwing up everything else and need time to work on fixing some of it before working on one of the groups they haven't destroyed yet.
Give it time, by 8.13 you'll have all the changes coming through along with reworked Aatrox.
