Don't get me wrong, I'm not butthurt about the fact that you don't like it.
In fact, I'm not butthurt at all, I just get a bit defensive at times.
As for the challenge part, if someone plays using all the best Pokemon of a type and grinds, then it wouldn't be a challenge either way. It's all in how you play, not where the game ends.
To clear things up.
I'm fine with your disagreement, though honestly, I was actually surprised about the negative feedback rather than anticipating it. I have gotten two messages from people who have liked the change, so I wasn't ready for your initial message.
