National Dex? Its a trap!
I found myself spending most of my playtime in ORAS just looking to complete things just for the sake of it. Some of the stuff wasn't even fun, I was just looking for things to do and it wasted a lot of my life lol. Now trading for egg moves and breeding, that's something you can build a community around.
I personally place heavy emphasis on strategy in my battles, I could spend all day envisioning plays and finding out what works and what could work as a unique play. Nonetheless I understand that not everyone shares that same utility.
I've definitely had Discord in high consideration. I feel like you might get some more immediate feedback in that kind of environment.
