Some Powers are clearly overpowered and some next to useless. I’ve respecced several times to try different builds, and found one that clearly tops all the others in terms of damage. Here’s a breakdown of my findings and views on the powers with a PvE Dungeon DPS -perspective in mind;
Best race: Tiefling or Human
Attributes: Int > Cha > Wis
Stats: Power > Crit > Recovery
Object: Provide sufficient control, then do maximum damage. Excess control is a waste, excess damage cannot be made.
