How significant is double dotting on Megaera as Destruction for an ACTUAL important damage increase that isn't just padding meters, but I know more embers are gained, but is it worth using the GCD for it?.
For example: You're killing red and green heads only. But blue head has 8 or so million damage taken (which isn't relevant to killing the boss).
Working on Heroic Megaera soon just wanted to know as there's no point padding the meters if there's no damage increase on the correct target.
Any math or relevant logs would be amazing.
