They removed Bane from SCH in the same expac they removed the Aetherflow cost of it on SMN, so maybe they should've just done that instead? SCH's DoTs weren't preventing it from healing, which is why their removal doesn't make sense. We can argue that ED is bad design for SCH until we go red in the face, but if their stated goal was because SCHs were focused too much on DPS and not enough on healing - why did they bring back ED and leave in Dissipation while removing things like Shadow Flare, Miasma, Miasma II and Bane? Miasma especially was a casted DoT, not preventing SCH from healing anymore than Broil or Bio? Miasma and Bane would fit perfectly in SCH's kit now, so why remove them?
