So doing a 3m boss where you afk mostly cause you have nothing to do and hardly use your abilitys should award you more than doing a 20-30m dungeon run where you have to use most of your kit? I see
Interrupts and cc in old heroics? You mean BC? There was some CC but even if it was standard practise, then most of those "old school" dungeon people still dont know what interrupt is, neither a def cd or proper damage rotation. Times change, so does the dungeons and the way it is run, while it might not "feel" hard, I do have to say, tanking a mythic plus high key is alot more fun than raid. In the end, its the matter of personal preference.
