I say that because I feel like they're a huge mouthful and are very wordy. I would personally prefer them to be renamed myself because it's a lot simpler and it sounds a lot better to me. Plus, they sound more like real attack names rather than the kind of comical names that they actually are.

(And to be completely honest, I would personally vote on getting all of his other attacks translated as well. It just seems weird to me to have German attacks xD)
