Wisdom's a sucker bet, and, like Embellish, is a waste of skill points. Besides, that's *still* tying up skill points, when I want to have more of them (or, optimally, skill points that do MORE for their investment).
It is true in the beginning, but there come a time where your catch up with your "wasted" skill points and level up faster, having more skills at the end that if you had not used that wisdom skill.
