It's a pretty shitty gimmick if you ask me. There is only one time I use it, after blocked corner mappa RC FTW. That's pretty shitty utility, I think 1 GP sounds fair. Considering the circus he has to deal with already in this game.
I detect a bit of resentment in your post. Again, it's not made clear, so I don't see the harm in clarification. It could literally go either way at this point. Especially considering that by default the P and K versions currently have different properties on CH. It's not out of the realm of possibility their damage would be changed as well. Sheesh
