Good news Pale, you might be getting a soul stone fragment for christmas, so you wont lose the skill.

It all depends on what you are going to use the mage for. From the looks, you could stand to lose fishing or alchemy. Neither supports the mage template.
But since I remember you being quite the fisher, I would use a soulstone to move alchemy to another character.

Unless you are converting to more PvM, then alchemy can come in handy for chugging pots. In THAT case, move fishing over.
