This is the achv needed from the 2nd boss of moshushan vaults for glory of the panda raider. I only need lightning fists, but Ive attempted this 4 times. all 4 times, ive used lightning fists on the boss both off and on epicenter.. and ive also used it while he was about to cast epicenter (charging it up) and while he was casting it... each time.. nothing.

The only help I can offer is the typical trade chat help, google it , but I'd read the wowhead comments to see if they provide any insight if you haven't already. http://www.wowhead.com/achievement=6...etter#comments

I did it a couple weeks ago with a friend + 3 randoms. It might be hard to understand - the tank has to master his tasks and all will be fine. There's nothing to it above what is written on wowhead really. You just need proper execution.
