All are correct here. Whoever initiates the leve is always the target whenever the mob has a choice. Meaning if you have to chase a mob and get ambushed, you're the target. If you pop a node, you're the target. If you're defending a point and the next wave comes, you're the target.

Also, straight damage and straight curing gives you nominal hate. I can heal constantly all fight and not gain any hate. However buffs such as Chainspell and Profundity will generate massive amounts of enmity. Same with casted buffs like Protect and Shell, especially AOE. Always use these buffs in hand.

I also find skills like Out of Sight and Soughspeak don't seem to make too large of a difference, although they do not hurt to have.
