It costs ~13 HP to fully vent the overcharge bar on Necro, Unchained, Battle Wizard.
Because of the longer overcharge bar it costs ~25 HP for Pyro to vent a full bar.
If these costs were equal the pyromancer’s theme of being ranged-focused would feel much better. Currently Pyro is still outshined by the other classes who have fun gimmicks. Having a larger overcharge bar that costs 13 HP to fully vent would make pyro fun, unique, and not be OP.
Thanks for listening!
