Yeah I kept Pally FC talent spread up there even though I feel it is extremely ill-suited to FC unless it has insane peels (mage, hunt) and is vs a heavy physical damage team. it's also garbage as a pug FC unless you spam 20g in consumables a game. I coniser a P-howl warrior better in most situations where a low mobility, turtle FC is required.
I could see CC and Fiery being decent as well compared to corpsemaker and crusader. I'd need to do some heavy math to determine overall damage per hit w/ procs. I do know corpsemaker and crusader does more dps vs the CC fiery build, but in a pvp situation, sometimes the RNG procs can be advantageous.
