Why use a Dragoon or Monk when you can use a Warrior?

[Rydin]

So why would you bring a DRG over a WAR? Why would you bring a DRG over a MNK or any other DD? Does it flat out demolish those other DDs in order to make up for the fact it has horrible defense?

Here is the issue....
All three classes can do damage and 1 (or multiple) other thing(s) well
So look at it like math
A = A set amount of damage potential
B = Tanking

A + B = WAR
A + C = DRG
A + D = MNK

At this point... all that needs to happen is B = C = D and all classes are equal....
So DRG has to be as good at its secondary thing as WAR is at tanking... and that thing needs to be as useful as WAR's tanking

So C = TP generation, More effective ways to stun than WAR has and enmity reduction
and D = increased TP generation, Speed, Speed, Speed, Elemental Fists (Which are INSANELY USEFUL... maybe the most underrated thing in the game right now) and also more stuns than WAR has

So if B =/= C =/= D then they are at least very close
