Aatrox rework before...?

There are 3 champions I can think of, besides Aatrox, that have been problems (as well as unbelievably rewarding for how simplistic their kits are) for a long time now... 2 were released 9 years ago, 1 was released 8 years ago.

2009 - Tryndamere, Master Yi 2010 - Garen

Those are three champions I still see banned and picked a lot. Aatrox is a bit weak right now, sure... but why not start reworking from the start, rather than picking random champions throughout the pool?
