It's the same with bucc energy charge. When you get fully charged, you gain 20 weapon att, and during that time, it only comes into effect if it's the highest damage buff you have on, so it won't overwrite apples or stoppers, but when they run out, energy charge's att buff will take over as the main buff.
So only place where stun could ever matter, is using barrage on shaolin's clones... That's pretty sad.
and even this is wrong, i was distracted when i replied this, where did u get 60%? theres no 60% on crits. critical damage is twice the normal dmg, and se gives an aditional 40% on that. so t ends up being an aditional 140% dmg, except by nls who gets an 180% extra dmg.
maybe, theres a multplier cap, something like damage cap, mayeb we have an 1000% multiplier cap?, but im shure taht u noted with barrage u get more than twice ur dmg per line
Stun mastery doesn't work like normal crits, in the skill description it says that if your target is stunned, you have 60% chance to deal 60% extra damage
