Yeah, but a wizards hit points suck, so it balances out really well.
Not necessarily. A toad gives +2 con. And con is important for wizards, so it wouldn't be absurd for a wizard to drop his second highest stat in con. So, a 10th level wizard could easily have an extra 40+ hits just from con. Not to mention they can craft wondrous items to make that even higher...
