Are you going with premades? Because everything outside of raids is easy with premades. And also, you're a tank. Play a healer or DPS and I'd be surprised if you hold the same opinion.

I've found most of the new dungeons to be more mechanically complicated than ever before, though mostly for DPS and Healers. Especially the last dungeon and the final trial. Then again, I started playing in HW, and I always held the opinion that ARR dungeons were actually mechanically harder overall than HW dungeons whenever I went back and did 50 roulette.
