In regards to mana costs....unless I'm not understanding correctly, the ability to cast in passive will allow you to regen mana during battle. (This is where you chime in and say 'who wants to stay in passive and watch combat' and me being a positive as a hookers pregnancy test says 'Roll an active class')

We're just at an awkward stage. People want content, any content with the old healing model they added was going to be faceroll. I'd rather redic. hard content while they're working out the kinks.
