It makes zero sense for the PLD class to have three different skills for AoE

[Shurrikhan]

How far are you willing to go along this path? Let's strawman for a second here, just as an illustraton though. "It makes zero sense for there to be more than one healing spell" or "It makes zero sense for there to be more than one class, all jobs should be able to heal dps and tank with a single button that does everything!"

Yes, that's a completely ridiculous argument, but at what point between PLD having 3 aoe skills and there being one job with one button will you be satisfied? Flash and eclipse have nearly opposite applications in spite of them both being aoe. One builds threat, reduces damage taken, and does no damage. The other ONLY does damage.

To be fair, this is much more alike to "It makes zero sense for a Melee to have two combo-breaking low-effect ranged skills" or "It makes zero sense for a Healer to have two GCD cleanses."

I use Flash commonly for its initial enmity and the extra healer AoE GCD's worth of evaded damage and find it distinct enough that I don't find it redundant with TE, but I see where they're coming from in this regard.
