I remembered FFXI and Ninja tanking. The utsusemi: Ni to Utsusemi: Ichi was kinda fun and required to pay attention. If done correctly, you had the best damage mitigation, if not you get slap around and had to try again.
Unfortunately it won't work in FFXIV because of the many monsters at the same time tanking and the difficulty to keep hate if you are trying to do something a bit complex at the same time (imagine that you had to input ninja mudra while tanking while the dps are spamming attacks at the wrong mobs).
