If Purification doesn't blow our Chakra stacks, then that means we can wait till we have 700 TP, use Purification and then use Forbidden Chakra, and then we will have probably no TP problems the rest of the fight, between Invigorate and Purification I doubt you would need to use Purification more than once. So that's pretty legit.

I think that if were talking about a Jump that is roughly 2-3 Seconds long, then you would only want to blow Tornado Kick if you just put up your DoTs as reapplying this while not in GL3 seems weak. So if ToD and Demo are up for more than 8 seconds, and the boss is about to jump. Blow GL3 with Tornado Kick and then stance dance until the boss comes back down, if you have time after getting to Couerl Stance then start stacking some more Chakra. If there are fights where the the boss jumps though, TP is usually never gonna be an issue.
