OP, when your group is breaking the ice and some pesky enemie dps is harrasing your healers and dps, use your limit break when available, it will bring protection for your group for a couple of seconds. Also when ice is 15 to 10% look for a escape route for your group and yourself. This is in case your group is not strong enough for PVP. If you continue to play Frontlines, you'll improve your gameplay and learn a few tricks from your GC and enemies. Good luck and happy hunting.
