As a new player with zero raiding or endgame experience who just joined for stormblood and played all 3 tanks to 58 so far my impression is that PLD is the only job of the three that feels somewhat thought out.

I started WAR, switched to DRK at 50 and now PLD at 58. Warrior feels so boring I can't figure out their vision for the job, there is absolutely nothing going on outside your basic rotation and even the rage dumps on the gcd don't feel satisfying at all to me. I guess its supposed to have good damage and cooldowns but the good feel isn't there for me and damage seems underwhelming.

DRK is kind of fun but feels kinda over the place, having the tank and dps stance pretty much on all the time and spamming dark arts all the time. It just feels weird to me and lacks cool "dark knighty" abilities imho.

PLD feels just better all around. Especially having different abilities off the gcd makes the job for me I guess.
