Hi there… I just make a lot of tests...it attack the first person, that´s true...but if the other hits him, he attacks the other one....I´d like to know if its based on total damage each one gives on him. That´s beacuse I made a game, and I use the concept of TANK, HEALER and DPS. But it´s difficult to use the TANK, because the NPC allways go on DPS.
