But it is a MMO? Don't get me wrong. I love the Final Fantasy series. And I respect that it's part of the FF franchise, but this is a MMO, whether you like or not. Note that Summoner and Red Mage were changed to fit the fact that FFXIV is a MMO.
My personal opinion is that tanks can be more than just DPS with simplified rotations. I'm not against tank DPS. I just think there can be more depth to both tank DPS and mitigation. I've only played 2 MMOs previously, but maybe I am a "MMO Chaser", I don't know.
I'm reminded of something from the Balance
