PBT drains mana, and without good reason as far as I can tell. Many chants in this game do not use mana (for example, run speed, dmg add, mezz reduction, etc), and I'm not sure why this was ever designed to constantly drain mana. It effectively acts as a malus to power regen. I believe this cost should be removed, or reduced as I don't see it serving a purpose; the power drain serves as an annoyance without any incentive to play differently. For counterexample: paladin's endo chant uses power, thereby encourages twisting to prevent going out of mana. Whether this is good design is separate argument, but it certainly reinforces a certain playstyle.
PBT doesn't appear to have any exploits to which a power cost would alleviate or eliminate. And furthermore, PBT is already severely restricted--it's 1000 radius, has a 3s immunity after removal, and requires specialization. It affects all realms, so should be fairly neutral in affecting realm balance, and I don't see it affecting PvE balance significantly either.
Thoughts?
