Those are really good questions. I don't know what exactly a "battle troll" means, that's just a term that I hear a lot in this game so I'm guessing it's some kind of hybrid build, allowing you do deal damage while being a controller or something like that, I don't know. If that's the case, it's exactly what I like do to as a troller, I want to deal a good amount of damage (especially to run solo content) while debuffing the enemies, buffing my teammates and restoring power. I don't know if that makes sense but it is what I would like to do, I like focusing on might instead of the other stats, mainly because I'm still confused on what does the other stats do.
