Yeah, but it's kind of boring to have to pick up Gladiator for every potential future tank class. And outside of provoke...Gladiator really is limited in usefulness. Convalescence is great but DRK will surely have an AOE enmity skill of its own and Awareness is far from a must-have.

Giving DRK its own provoke means it doesn't have to use gladiator. It also means they can give other classes a provoke without Gladiator. Other new tanks. Giving the option of one or the other for Warrior, if they implement a "select two" sort of cross class thing instead of leaving them fixed. You could envision Dragoon being more interesting as an off tank sometimes if it had a provoke and some hypothetical DRK skills to go with it.
