Hello
Bursting shot is useless PvE ability unless you have legendary which increast its dmg by 800%. Since then it nice AOE dmg boost + interupt and even Binding shot trigger in mythics and M+.
BUT there is one issue with this ability. And that is it also dispel targets every friendly DoT effect when disorienting which make it total useless again. Unless your entire party isnt using any dots.
I think it needs glyph which removes disorient from this ability or atleast that dispel effect to make it little usefull even with legendary.
