I'll also say that if I were Yoshi-P, I wouldn't respond further to this issue. If Yoshi-P did give you an additional response and told you something along the lines of
"Thanks for the feedback, as expected there were some players who felt negatively about the changes, but that was only a minority of players, so we're sticking with our design,"
...would you be satisfied? I can't speak for you, but I'm guessing most of the pro-Kaiten players wouldn't be. The response they want is a response they agree with, and they've already made it clear they disagree with Yoshi-P's stance. And those players are going to pick apart every last word of what Yoshi-P said, which will fuel a new wave of backlash. The smarter move is to say nothing at all. Especially since the message is only directed at a small subset of players anyway.
