Apart from tier gear, there's very little good healing gear that is mail. Shaman should have the option to request cloth gear.

I'll disable auto passing by default next update.

I have no way of detecting which spec a player is "in", thus can only use the class to do auto passes - in which case it's better not to have it. You can disable auto passes already though.

Fixed in v0.2.0. Thanks for your report.
