Anything like that to smoothen out her pattern would be helpful. A faster attack frame (so she hits sooner but doesn't increase her attack speed), ult procing the q mark, ulting someone while q is in flight to them causing it to hit instantly (so you don't dash on t them and auto them before the mark lands and then have to wait and auto again), having max attack speed against marked targets while inside shroud (so she would always be able to quickly proc mark against someone in her territory), leting e proc q again, letting e make a q thats in flight to a hit target instantly land and proc (so she could reliably q-r-e and know for sure that all of the damage is going to land and land smoothly without awkward dicking around), let procing q reset the auto timer (so that you can q, wait, ult-auto-q-auto without being stalled while waiting around for the attack speed to hit the second q mark)...
There are a lot of ways riot could make the whole pattern feel better and more reliable. I'd rather they do something like this to bring akali back up to par rather than 'lol heres 3% more base spellvamp on the passive' or something that could increase her winrate in a not very satisfying way..
