I don't mind it
It's different from the server merge which was trying to destroy bonds between players at first.
It's just the option to only play with people from your timezone, and I don't think that's a bad thing.

I transfered to the EU recommended server and I don't really regret it.
I lost my NA LS which is sad, but I made many new friends who speak my language, our LS grew and there is so much to do during the time I am online
Well, I understand people though who don't want to give up the bonds they made.
But if they introduce regional servers in 2.0, it would be optional to transfer there, nobody would be FORCED to so there is no reason to oppose the OPs idea.
