Every iteration of RDM as a tank I have seen is just a bad clone of DRK... We have a magic based Tank already, shoehorning a FF classic to suit the desires of people to scared to Tank as a Samurai is simply destroying the identity of a second FF staple... The reason there is no sword DPS is because iconically the sword is wielded by heroes, heroes don't stand behind the enemy, they face it head on.
Aspects of Samurai would be completely lost if they didn't have things like the Samurai challenging their foe to a dual, the use of medium/ heavy armor, the tenants of Bushido i.e. death before dishonor... (cutting people from behind while they faced another was kinda not honorable)
In my unimportant humble opinion the "desperately needed" sword DPS would be much better served by RDM and BLU. Flame General Raubahn Aldynn's dual wielding heavy sword use would be perfect for the Kirito try hard wanna be's, and even makes sense given the heavy implication we will be focusing on Ala Mhigo soon.
The same could be said for RDM as his foil Ilberd seemed quite formidable with En-Fire and what appeared to be an advancement of the 1.0 sword skill Red Lotus Blade.
