There needs to be some form of limitation for skill spam for non-magical classes too, though I agree that the management options are limited in comparison to MP stuff.

Easy fix: Add in some TP restore potions and TP regen food.
Determining which level recipes they are would be a more difficult thing though. TP doesn't scale with level like HP/MP do. Not only that, it's a lot harder to quickly burn through your TP than what it is to quickly burn through your MP from what I've seen. Such adjustments would probably call for slightly increased TP costs of certain skills.
