Investing in Recover Energy will do wonders for any mage that doesn't rely on Leech to recharge their FP/ER.

With your current spell list, you have some awesome battlefield control. Move 2 may seem slow on Shape Earth, but, you can drop people into sink holes with it, raise barriers to protect yourself, and give your archers the high ground.

For expanding your spells list, it seems appropriate enough to go from the earth/stone spells into some of the metal ones. Nothing like blunting swords or ruining armor!
