Tepig doesn't need Close Combat, it already gets head smash and hammer arm. Gothitelle? You can be a fan of the poke all you want, but that's just totally unnecessary. It's not part fighting, it's not even an agressive looking Pokemon with high attack like Zangoose, an example of a non fighting pokemon that learns CC. Also Tepig is slow, and CC is a move for very swift pokemon like infernape and gallade.
