The health cost is higher than the spellvamp because it is the only real restriction to her ultimate. The lifesteal is not meant to actually heal you, it is just meant to compensate the cost. Amok is a damage steroid, not a lifesteal steroid. It already gives uber-damage. So if it gave uber-duel-sustain too... Heck, it's pretty hard to figure out the real potential of that ultimate.

The changes to Fury are... not really what I envisaged. I mean, it is completely different. If I understand well, Fury would not increase if Haruka keeps attacking? But Amok should only be activated when she is attacking anyways.

In fact, % current health cost was my original idea. I changed it because it made her ultimate broken when low and useless when high on health:

- At low health, the cost is almost nullified. 60% extra AD and 30% extra lifesteal at no (almost) cost is op.

- At high health, a % current health would actually be more impactful than the current AD scaling cost. For example, if you have 250 AD and 2000 HP. At max rank and max Fury, the AD scaling cost is 60% x 250 = 150 health per second. This is equal to 7.5% of your current health. 15% if you are mid-life. Basically, it means that Haruka can only viably use her ultimate when she is low. But when she is low it becomes op.

- It also basically removes any interaction with defensive items. Even health wouldn't be a "protection" anymore.

For the duel sustain problem, the missing-health-scaling lifesteal (see the posts below) seems to be a good solution.

About Fury, I'm thinking about increasing the generation from 10 per second to 20 per second, so Haruka only needs 5 seconds to reach full Fury. It is most likely that she will never keep it activated for 10 seconds.

Still, thank you for posting too.
