Overall I think"layering" is necessary for the first few months and so far, from what they have shown, Im convinced it's going to be buy classic wow gold gone before Stage 2. My only issue is that a massive chunk of this Vanilla WoW Classic community is not getting the beta, but the retail players are getting it.

A good deal of the vanilla community is coming from private servers today (my self included, although I am not as hard core as a good deal of those men ) and on personal servers that's never been thing.Yes sharding is poor for Vanilla at the beginning but I think its good for its longevity. Blizzard clearly needs new players to play with Vanilla because a portion of the veterans who used to play with wont come back cause life. If the first experience for these players is a laggy game since there is so many gamers in which you cant do shit now imagine. . .They wont stay long.

I think honestly and this is really taking a LOT is a huge turn off for me personally. I am glad that they are saying that phase 2 will, layering cheap wow gold classic gone. Still don't think that it ought to be in WoW Classic in the first location. Think that is why the community isn't pleased with it. 
There were rivalries. I believe sharding will kill that sense of community and it's not gonna become a multiplayer match. It's gonna be like WoW Classic in which you play on your own and set out of necessity. You can be a dick bc nobody understands you and is log out and log back into a new layer.
