we need a sword dps

[Katana190]

Not really. The main reason Warrior is essential is because of the Storm's Path/Storm's Eye debuffs. These allow Warrior + Dark Knight and Warrior + Paladin to be more optimal with any combination of healer and dps than Dark Knight + Paladin.
A 4th tank might make the current situation worse or end up leaving the current situation mostly unchanged. Warrior + Dark Knight/Paladin/New Tank being optimal is not a situation I want to see and Warrior/New Tank + Dark Knight/Paladin is hardly better than the current situation.

On the DPS side... they've done a fantastic job. Why doubt them on Tank and Healers? Hell, if you want to argue about the most optimal composition for DPS raiding its actually 2 Mch's, 1 Nin, 1 Drg. But we don't see that, like at all.

The healer problem is more because of how underpowered Noct stance shields are for PvE content in comparison to Scholar shields. White Mage + Astro(Noct) is just not as good as White Mage + Scholar or Astro(Diurnal) + Scholar even though it is still viable.

This isn't the only reason SCH is so viable.. the noct AST shields are actually stronger then SCH shields if not crited. Its all the utilty it brings, being able to spread a single target shield onto the whole party + burst heals + pet healer + highly sustained DPS while keeping HPS up. Its the same for WAR. WAR isn't only viable for its 2 debuffs or DPS, its actually very close to DRK DPS. What WAR does great is its self sustain on top of all its utility, having one of the most on demand mitigation skills in the game on top of its ability synergy.

I'd rather see Samurai be a Katana wielding Maiming gear wearing slashing DpS with its main combo applying a version of Storm's Eye/Dancing Edge with one of its secondary combos applying a version of Storm's Path. This should solve the "Must have a Warrior" problem.

I'd like Red Mage to be a Rapier and Buckler wielding Scouting gear wearing melee piercing/magic support DpS.

Your literally describing WAR as a DPS. Also 2 DPS? This is shooting the tank population in the foot.

Depends, are you fine with ALL the queues being just as bad as PVP queues. Because that;s what gonna happen if they release just DPS classes.

I'm glad someone cares. As much as people say not many people switched from DPS to DRK, it did do something for at least the first few weeks and peaked some peoples interest in changing roles and sticking to it, we can't just shove that point away.
