Bro you are out of your mind if you think the majority of pug groups at the 20 level have two DPS doing 30k in a boss fight. Even with Power infusion, that’s rare to see.
And you’re playing a DK who can grip adds in - not a luxury every pug group has. This boss is overtuned, and that’s OK to admit. The highest key done on lower this week is 25. The last tyrannical it was pushed 2 key levels higher with less gear - and they nerfed those bosses anyway.
