It is stated that her passive locks out the enemy health for 4 seconds on Akali's first hit to that enemy and it has an on-unit cooldown of 8 seconds. The goal of the new passive is not to deny little by little healing overtime over longer periods but to deny the burst heals of champions like Soraka. The passive creates a situation in where the enemy (if he survives the initial rotation) will have harder time to survive Akali's next rotation (not just reset back to full health with heals). This gives her a reason to go on with her mission to kill her target instead of escaping.

Regarding the theme of the passive, I plan to make it so that one of her kamas shreds through physical objects with ease while her other kama cut the spirit (therefore dealing magic damage and hindering regen)

Q: on last hit ---> on last basic attack hit (the timer resets on basic attack hits...sorry)

The changes to her W and E makes it easier for Akali to dodge skillshots inside the shroud (given that she can now be seen for a while). I think i went overboard giving her E a reset on champion hit (I will remove that). Placing the mobility on E rather than her W gives Akali better emphasis on using her W to stay in the fight while having the choice of using her E to disengage when the shroud does not provide much safety.

I made the changes in R (reduced range and reduced cooldown) to balance her mobility. (She can waste E damage to be in range to R to a far enemy tho)
