Outside of CC, I assume, WHM is only good for its LB and harassing enemies with the Kappa spell. Want to know how to beat the lb? Purify. It's as simple as that. Meanwhile you have MCH with the .50, SAM with an insta-kill, Ivuln tanks, SMN auto-turret, and DRG orbital strike. I get that 6.0+ is the death of whm being viable in pve, but having 1 useful spell in pvp is the only thing keeping it from becoming a bench warmer. Hell, it doesn't even have a useable healer spell.
