as a dancer that currently goes to battles, we hate when we know that the judge knows nothing. In the dance worlds they're very specific with the judges, even if its a locking battle, you have a judge that can dance locking, if its waacking or breaking, is the samd. They try not to put a locker judging a breaking battle. So tbh as a dancer i would be pissed if i saw those types of judges but yeah, this is television.
