How does killstealing work? Isn't a mob tagged to whoever hit it first?
I know if npcs attack it if you outdamage them you take "possession" of the mob, but if its two (or more) players, every experience I've had indicates that whoever first lands an attack gets it.
Why would someone get pissed if you kill a mob they've already tagged, they still get loot/credit for it, with minimal work.
