Bane, miasma, and Shadowflare were maintainence buttons in the same way that tank defensive cooldowns are maintainence buttons. Or SMN DoTs. Or any of a dozen hit-on-cooldown (in most cases) damage abilities on dps classes were. The fact of the matter is that they made dealing damage on SCH more engaging than a 1 button spam. It wasn’t perfect, and I would have liked to have seen improvements, but these aren’t improvements.
