If you don't do savage or ultimate, balance at the top end does not meaningfully affect you. Normal content parses are so utterly worthless that it's a wonder they're even saved. The chance of you dying to golbez's enrage is so hilariously slim that it'd be an achievement in of itself. Anything below that has even more lenient dps checks. I cannot tell if this is salt that dark knight doesn't have an effortless dps opener or just stirring the pot. Also get over yourself about the kill times, that affects literally everyone. Boss dies just before final sting registers? Tough luck, join the club.
