We need a Greatsword Dps Class!!!

[Enkidoh]

But why deny potential new classes and jobs solely because of the weapon type? Doesn't that seem a little short sighted and lacking in the imagination department?

Except that's the whole point of the Armoury System - class/Job revolves explicitly around weapon type being that class's very identity and there usually isn't any weapon crossover between classes - why else are the class/Job icons usually depict the weapon it uses after all? (There are couple of minor exceptions to that though, usually prior to a class being implemented, such as Edda's scythes being given to various classes as diverse as CNJ/WHM long before RPR was added, but those are unique exceptions to the rule and are not indicative of new classes being added).

Another thing to remember about wanting Jobs from other FF games to appear is, they may not always fit FFXIV's gameplay as a single player game and a MMORPG have different design paradigms (like Mime for instance would be completely useless here in FFXIV, but is an interesting gimmic Job in certain single player FF games like FF Tactics). Many Jobs that do not literally appear by name here in FFXIV also may actually exist anyway in another form in that their ideas/weapons/abilities have been rolled into other Jobs, like elements of Berserker for instance have been given to WAR, and that AST is pretty much Time Mage in all but name.

As for your 'great sword DPS' idea, DRK is already the 'great sword' user in the game, so I am pretty confident to say that you will not see a DPS-specific variation I'm afraid (after all, DRK's victory pose is literally Cloud's victory pose from FFVII, so that pretty much underlines that you will not see Cloud's Soldier/Mystic Knight 'class' appearing here I'm sorry to say).

I have eaten my words about new Jobs in the past though (aka, RPR, GNB), so... may I be proven wrong! :P
