I disagree with you about the mana draining thing, mana vampire totally drains your mana but is a tier 7 spell, incredibly expensive. Mana drain can still be a pain, but its far less effective - and anyway, what *good* mage is going to spend his/her time draining mana whilst they are in the middle of being LP'd over and over. If this contant mana draining wasnt going to be a problem, then that mage is taking time and mana away from offensive casting. I honestly dont see it as that big of a problem. Your mana regen is still reasonable with just fifty focus tbh

As for dropping anatomy, ive done it on a few characters and its a bit of a pain, youd be alright with heal potions and confidence spamming, but frankly you dont want to be wasting mana all the time on confidence

110 Fenc
110 Parry
110 Bush
90 Heal
110 Ninjitsu
80 pois
90 Medi

If i were you, id ditch the parry and go for anat instead. Parry would be nice, but anat will have a 2 fold gain - more damage output and improved healing. Without anat, (or tat) your going to be doing no damage against someone with decent poison resist // cure potters
