Funny thing about Amuk and her passives. If she has 1.00 attack speed she breaks even (unless you count the increase of health costs) I think it would make more sense to increase the life steal slightly as she is likely to be taking damage. This is an ultimate that is designed to work while in combat attacking people. I feel as if it would be better if were like this.

Cooldown 10

Cost: 1 % Current Heath per second per Furry

Toggle on: Haruka gains 15%/20%/25% lifesteal and 20%/25%/30% Bonus Attack Damage

Haruka builds 8/6/4 fury each second unless she has dealt ability damage or performed a basic attack in the last 2 seconds.

Toggle Off: Haruka Looses 4/6/8 furry per second.

With this you are punished for ulting and being CC'd, however there is no imidiate downsides. However I did increase the cooldown to reward counter play. The cost is in current health so the lower health you have the less it can kill you.
