The Akali rework was just in the early stages of it, so its not set in stone.
Its predicted that it will probably only come out like at the end of S6, which is a long way. They still have Poppy Urgot, Taric, Yorick and Shen etc to work on.
Everyone knows that Akali is in a long due for a rework because shes in a pretty bad spot atm, in the meantime Riot still need to add healthy power back to her kit because 5.9 obviously wasn't enough. What i mean by healthy power, is to buff Akali in a way that isn't going to make her problematic again, so avoid giving suggestions such as damage buff, cast time removals or making spells more easier to use.
My suggestions at first is to re-look into the strike-through that they added 5.9, perhaps make it more potent, or reduce the melee strike-through range to be a flat 100, I honestly don't like it how to pushes you out of AA range at 200.
Second Suggestion is to buff the movement speed boost on Akali's W that was introduced at 4.18, the movement speed boost was left undertuned on purpose at lvl1 because she still had E being able to proc Q and 800 ult range, now that they are both gone they should add some power back into her ms boost on shroud at early ranks because it is really underwhelming. The Initial amount when it first hit PBE was 60/70/80/90/100% but then they reduced it too much to the one on live 20/40/60/80/100%.
