Darth Zannah vs Barsenthor

Vitiate had most of his power elsewhere, Bane didn't. 😬

That sounds a lot like your opinion instead of what the quote you just posted said. Bane was obviously planning to attack offensively, and was surprised by Zannah.

He was building up his power to attack. He hadn't done it yet, so the power was still available to use in his defense.

Thor wins, Force feats like they went out of style.
