Thanks for a quick and informative response, stranger. So - follow up question. For my fiancee who is doing a damage-focused savage-sortiledge human fire mage, would she be gaining the bonus to critical damage from adding points to two handed and using a staff with her spells? By your previous response, I assume the answer is, in fact, no. It seems counter-intuitive, though!
I mean, if that's the case, it frees her up to pick up another tree, perhaps polymorph for points into wits and great mobility, or even huntsman to try to stack +% damage from elevations.
