With up to 80% critical hit chance plus fire, and they use sd to close the gap when kiting along with melee you don't always get a chance to reload and do the combo a 2nd time. If they are an experienced nuke build theres times you barely get the option to perform the combo even once before you get bulldozed. Now if they decide to raise the cap and going on the bless skill rating the next level for bless will be 100% critical hit chance lol and then it will be insanely OP if that happens.
