Blm is pvp if played properly will more than likely be a force to reckon with. AoE CC is, and always will be, the MOST powerful thing you can bring to a group in pvp. Swiftcasted Sleeps/Freezes for insta aoe cc, Blizzard 1/Lethargy for Slows. We might not be the chain-casting dps turret of doom you imagined but BLM will be amazing in a group.
