Teddiursa would be about 8 going through Viridian Forest. I've got one PKMN right now, but everyone seems to have between 1 and 3. I'd just say don't start with a full team all above 10. You could have one above ten, but don't OP yourself. You got it, right? So far everyone's doing a good job of not god-moding.

Also, manapool, seriously? Haha! Top percentage. And don't worry. Carter's a happy camper now, but shit's gonna get real soon enough.
