It's got nothing to do with WAR's really. That's just one result of the main problem, that raids don't do enough damage. 8 WAR groups don't affect the normal player, they're hardly going to be denied a slot in PF because everyone's stacking tanks, most people still take the usual 2/2/4 comp. What does affect the normal player is the boredom of pressing 1 button all fight and throwing an occasional aoe heal at the raidwides that tickle you once in a while. Even if you nerf WAR healing to the ground, that won't change.
