Having a moth pet makes questing in some areas difficult since I refuse to make my pet kill others of his kind to begin with, and the fact that they're all nonagressive makes it that much worse.
This proff is expensive to level, and with 3.3 changes making you the group tool (and recent hotfix providing more mats for every DE) it promises to make even less of a profit. It does not even provide a midlevel rare BoP piece or a high-level BoE piece that alot of the other proffs do.
