Jobs are not the only type of content. Besides, some of the more strident members of this forum are endlessly trying to convince themselves that WAR is the only well-designed tank job in the game. Heaven help us all if SE introduced another "inferior" tank.

There is no OT "role". It's an arbitrary, player-created designation which depends entirely on how your group decides to split up the tanking responsibilities on a given fight.

I'm relieved that RDM and SAM turned out to be dps. Neither would have made for a unique tanking aesthetic over the existing tanks. Casters previously had the least variety in terms of jobs (BLM and SMN). Adding RDM into the mix not only helps with that, but its also a great way to get melee orientated players to try out casters, by bridging the gap between the two playstyles. I'd also be interested in seeing if this opens the doors to new caster synergies, allowing for a caster-heavy raid comp.

I'm happy with the introduction of SAM as melee. I like having the option of being able to jump into a sword-based dps for offspec purposes, and the charge attacks sound reminiscent of Cyan from FFVI. Also, with the addition of a fifth job with slashing, the game designers will have to think twice about letting WAR effectively be the sole provider of the slashing debuff. I'll be interested to see how it synergizes with the existing melee jobs, as well as the tanks.

SAM and RDM start at lvl 50, so I'm not entirely certain how useful existing tank mains at 60 will be to alleviating queue times, outside of the once-a-day roulette. It'll be an problem regardless of whether your secretaries have booked out your Stormblood schedules or not. Well, serves them right. T-they'll see! *shakes fist*
