You could switch the places of Akali's passive healing and W Movement Speed increase
Passive - Twin Discipline:
- First Strike: Restores 5 - 60 (+0.6 bonus Attack Damage)(+0.45 Ability Power) Health -> Grants bonus Movement Speed for 3 seconds and ignore unit collision
W - Twilight Shroud:
- Movement Speed: +20/40/60/80/100% Movement Speed --> Extends First Strike's Movement Speed duration while in the shroud
- Healing: Now restores Health on cast
You'd have to work out the numbers, but it might make her a little more Assassin-y and less Drain-Tank-y.
