Warrior Trait Attribute Bonus
So I’m either missing your point or you are flat out wrong. Crit damage and burst damage are two separate things. By putting 20 points in discipline I get 20% extra crit damage and 2% extra burst damage. They are separate stacks. Burst skills will do more damage as you increase power and crit damage in general, now on top of that you are giving them added damage from the trait line.
Essentially if at 20 points in the trait and you have a burst skill (skill activated via f1) that does 100 damage, you will now do 102 damage base for that skill. Now if you crit that is extra damage added on top of that. This means you get more damage from the discipline trait, over just stacking it on the side.
