You're not going to be spamming attacks in pvp (unless you fight club) keep the burstier attacks and drop a light attack (or two). Also pick up a ranged attack from your epic/patron.
For Fightclub: ThunderKick and Brawl with high enough recharge so long as you have two procs in each attack. If your recharge isn't high enough then Thunder Kick, Brawl and Storm Kick with two procs each is all you will need.
For zone and non fightclub dueling: Storm Kick, Crane Kick and Eagle's Claw, with a ranged attack or two, or webnades.
What is a good attack chain for Martial Arts in pvp? Esp...with the new changes. I'm trying to figure out what the best dps chain is without taking too many attacks. So far I currently have Storm Kick, Cobra Strike, Crane Kick, CAK, and EC. I need to drop one...maybe.
