what do you think is the worst kpop group name change? what about the best? something that actually was an improvement?

Someone mentioned groups with numbers in them.

Those are absolutely annoying so they're in the worst category as well.

What are we doing, algebra math?

Yes, I'm fully aware Babymonster is sometimes written as Babymons7er, too.

See what I mean? But, I deliberately choose to write the name without the number like a Normal, Sensible fan.
