SAMURAI SHOWDOWN

[Radacci]

I'm guessing you don't remember DF when 3.0 launched. It was nearly impossible for tanks to queue, and DPS had the easiest time for awhile.

that lasts for a week, then back to square one.

RDM (° ͜ʖ ͡°) and considering that RDM can cast spells, they could back off the boss when necessary. I think RDM is their most solid healer choice out of the remaining popular jobs: SAM, RDM, BLU, DNC, BST, and RNG. That's not to say they couldn't make an entirely new healer, which they might. I also think DNC makes for a really great melee support, which is currently missing. I've never really considered DNC to be a full blown healer in any game even in FFXI where it was more of a solo class that you could do small content with. Dances also seem better suited to functioning like BRD songs, giving the party an array of different buffs or giving the enemies debuffs. We also need a pure DPS ranged job, so I think RNG would fit this nicely.

what's the point of making rdm, healer? there's already whm. whm/rdm/blm are supposed to be different - well rdm is supposed to be able to do multiple roles, which isn't going to happen, so it's more likely it will be a melee caster.
there's no support jobs, only certain jobs with some utility skills. if they add dancer, it will be a dedicated healer or dps, or maybe merge with something else, and make a new job. (such as with ast)
