Bring Back National Dex - Why must it be like this

I mean, you do you, I'll do me, and we can both be civilised people about it.

Personally, nothing about it seems particularly appealing to me; what does it even have going for it beyond the sheep? Dynamaxing doesn't look interesting at all, it's just Pokemon getting bigger.

If you're excited, sure, that's fine, obviously, but I just don't really get why.
