Just got this, 870, no socket. Gave me 25K increase on Simulation Craft. It scales very well with CS and other buffs. However, it has a debuff that you can trigger the 15 sec CD to 5 min CD as a chance per use and the debuff lasts for 30 seconds. How do I use this? What are the chances per stack to trigger the 5 min CD? Should I macro it with my BC? I think it should absolutely be used inside CS window for maximum DPS. Anyways, any ideas or tips would be appreciated.
