2 things about bombs
I don’t feel that way, skill one deal massive dmg in power base build adding bleed would make it imbalace. Fire bomb is great combo field, you can grant aoe might, fire armor for yourself and burning is always strong even with 0 condition dmg it deals 350+ damage per tick. Skill 3 gives 5 stack of confusion, witch again with 0 condition dmg deals 500+ damage. This two should suffice in condition dmg build.
Said trait is clearly made for granade’s when you dish out 3 of them per second, but ill will agree that 6% is too low, but no more than 15-20%, not every class have to be able to max out bleeding stacks.
