I think for small changes these are reasonable. My suggestion was
Miasma and Miasma II (rather than an upgrade, but to replace or be in addition to Art of War, I don't like Art of War), so the AoE DoT and the single target.

But an earlier Energy Drain & Aetherflow I think would help lower level folk. And I'd be happy to get Bane back.

This won't be a proper fix, but I think should be good enough to hold us over to 6.0 and are relatively small changes.

For balance then, they can give a little extra to AST (they're complaining about the Card nerf anyway) and why not give White Mage Aero III back? And return some of its lost potency on Holy. This would rebalance the rest and give them something back while not requiring any thing too big for a patch.
