Warwick Potential Balance Changes

Swapping WWs passive and his e could work as a means of both nerfing him without breaking him. Making his passive Blood scent which would grant him a flat 50% increase to movement speed when enemies are at 25% h (lvl 1) 35% h (lvl 6) 45% h (lvl 11) and 55% h (lvl 16). While making his eternal thirst being his e that has a passive and and an active. Passive: Warwicks basic attks heal ww for (2,3.5,5,6.5,8) health per basic attk stacking up to 3 times. Active: Warwicks passive bonus is doubled and deals magic dmg for the same amount for 6 seconds, killing an enemy champion increases the duration of the active for .75 seconds. 100 mana cost at all levels with a 20 second cooldown. Along with increasing his base health to 605 and dropping his attk speed to .61 from .679. Would make WW caple of the classic 1v1 burst a champ down but would make longer fights harder to have a guaranteed win with due to not having large sustain for the whole fight.
