Is new ww passive on-hit or not?
Eternal Hunger (Passive) Warwick's basic attacks deal [8 + 2 per level] bonus magic damage. If Warwick is below 50% health, he heals the same amount. If Warwick is below 25% health, this healing triples.
Does it proc (damage and heal) on Q and ult? (ie. is it on-hit or specific to AA?)
Does it heal when you are above 50% health? (for maybe less that 100% bonus magic damage, ie. is it really fixed threshold of 50% and 25% ww health or is it something like linear healing from 0% to 100% up to 50%, etc...)
