I didn't realize that the global cooldown didn't apply to sorcerors. Sorry my fault.
Lets ignore the fact that you get a free interrupt with your force leap to shut down force lightning or crushing darkness, depending on which he's casting.
Lets also ignore that Affliction takes 3 seconds to tick, as well, right? So the procs he can get up in the time you're leaping back onto him are... ... .... 0?
