Form a team with 2 BLM, a PLD and WHM. sprint rush the enemy team, and Swiftcast sleep with the BLM's on 3/4 enemies. 1v4 the remaining sucker using stone I or blizzard to slow them down with the tank stunning. rotate sleeps with the blm's and continue to 1/4 until people are becoming immune to sleep. Spam holy to lock enemies down for 6 seconds(3 straight casts of holy). Proceed to reuse fully potent sleep again. Seriously... pvp isn't fun at all until they nerf the hell out of sleep, which probably won't take long.
