Kalgan posted the following information recently:

Two things we'll be making improvements to in the near future (although these aren't likely to make it in on time for 2.3) are having iceblock be trainable (to make sure all mages have it as a tool for pve encounters and to open up other trees as being more viable options for pvp), and to-be-finalized improvements to mana issues in longer fights.

We also plan to buff mana gems, although I don't see that as a "fix", just an improvement that needs to be made regardless.
