TBN is no match for HOS/ST overall, because they continue damage negations. 1 hit of 25% damage removal from a buster doesn't make it super good, it's pretty terrible. HOS has far more value for simply doing more for auto attacks after a buster with no drawbacks. Even Sheltron offers that value as much.
No. As long as you do not overcap on mana you do not lose damage at all, full stop. So long as every TBN that you cast is popped, mana usage is equivalent to warrior beast guage usage. In fact, simpler, because you have less generator combos to worry about (no upheaval and infuriate to worry about).

Further more TBN does not block 25% on one hit. It just absorbs up to 25% of your maximum hp over the following 7 seconds. Just go back and see basic posts comparing the math. Heart of Stone is literally a joke compared to TBN.
