Yeah, that would be a useless buff.

Now that I've thought about it for a while, I think the following changes would be fun, and practical, but not OP:

1. Chakra stacks automatically every few seconds, 5 maybe, IF you're in Fists of Focus. (Yes, a new Fists form.)
2. Reduce the Potency of Forbidden Chakra, (WAIT, DON'T PITCHFORK ME!) *but* have it grant GL3.
3. Change Purification to an ability that removes all TP costs for a certain amount of time, 15 seconds maybe. (This would still serve the current purpose, but also allow it to have an alternate use for AoE spams.)
