Ditto. Her shape change ability really is useless. I've only used it about 2-3 times, when she's out of mana and I have no pots.
Its not even worth changing when she's being attacked, as the bear makes a useless tank and your better off using Mindblast/CoC or similar. Waste of 2 talent points. As she's the only damage-spec Mage in the game, its not like I have any choice either.
On my next play through, I'll respec her. I don't mind "modding" on my second/third playthrough to make things more interesting, but I'll stick to the "Vanilla" game on my first.
On a similar topic - rolling a warrior - why do you *automatically* have a point put into a sheild talent? I want a 2H bloke, and I have no intention of wasting a point on that...respec ahoy!
