Vengeful and super bla bla slash

[tubbies]

Is anyone not getting any damage from these attacks? It seems to me that the only thing these 2 skills are doing is the knockback. The damage from using these skills seem insignificant at best.

And does anybody know if the damage from these 2 skills a fixed amount per level or a percentage of your weapon damage? Makes more sense for a 2handed weapon to do more damage with the skills rather than doing the same additional damage as a 1 handed weapon.
