Question #173: "One thing that I still don't completely understand is how threat will work in PvE situations. Is it just based on whoever is doing the most damage at any given time or are there skills associated with threat? Is it a profession thing? Along the same lines...if there is no dedicated healer, who keeps the group alive? How?"
Answer: "Threat is largely positional based, creatures like to attack things closer to them. Some creatures have different behavior and will attack things at random these creatures are scarier kill them first. (There are a lot of other factors but positioning is one of the most prominent) As for healing when everyone call heal and res the answer to who is keeping you alive, is everyone if your health is getting low you pull back and heal up. If a ranged monster is raining ranged death on your party you use reflection skills, or keep the monster shut down, or everyone spikes that guy down. ~Izzy"
Answer #2: "There is no skill based threat. It is based on a variety of factors, one of which is proximity. The group works together to keep itself alive. If you draw aggro use your heal, dodge, use defensive skills, try and lose aggro if you have used up that stuff. If you can't get an ally to use a cc skill on the enemy or a support skill that might help you, for example:
Debuff the enemy with weakness so you take less damage.
Cast an aoe heal near you.
Apply a protection, aegis, or other boon to you.
Blind the enemy.
This gameplay is just a more team oriented, and fluid version of combat that requires more interaction and less dependency."
