To be fair this is more like how MC worked when it was the level 63 dungeon; those mechanics HURT. Difference is that back then we were guaranteed a healer and tank.
My problem is that these dungeons were never designed to be run with only 3 people. Yes, MC was 3-man last time we had it, but it was so painfully easy it would have been a challenge to die even on purpose. Honestly, I do think this incarnation of MC is still really easy, but I did notice things can actually hurt me now.
TR on the other hand is unforgiving. If you mistime your dodges at all, you're dead. The TR I remember was fun, this is just frustrating.
