After 1 (arguably 2) expansions what is square trying to achieve with WAR (and PLD)?

[Aravell]

You don't understand why WAR absolutely has to keep something we've had since 2.0 with Bloodbath? How about because we don't want to lose any more tank identity?

You are attributing WAR's identity to a cross-class skill, that would be like saying PLD's identity is out of combat Raise and being able to cast Stoneskin.

WAR's identity is self-healing, which they still have a lot of without an ability that makes them immortal for 4 GCDs in big pulls.
