could you explain how these three equate to playstyle please....
Momentum
Adrenaline (not sure if this is acceptable)
luminecence
then i'll pick 
Momentum is all about combo hits. You start out with a penalty to hit, and then for every hit you get slightly better odds, until eventually you're on such a roll you can't miss.
Adrenaline plays similarly to a monk in DnD. Three attacks instead of two, no armor or weapons allowed. Kung-fu stuff only. Bronze knuckles are acceptable at later levels.
Luminecence is like a... cleric? I dunno. Point is, you can give light based buffs to you allies (level 10s get blessing on a stick), and you'll eventually learn a weak version of holy flash.
