With more corss servers merged into one place
Why wouldn't blizzard consider actually opening up other cities for players to congregate in, rather than endless shards of Orgrimmar and Stormwind?
1. Expansion city should be the one with a lot of shards as everyone will converge there.
2. But back on Azeroth - why not have all the other cities have AHs and portals and basically designate a faction city as the go to place for a bunch of realms - off course you can set your home city to somewhere else, but this is what it ends up being.
how you ask? Well if your realm's city is now Exodar or Silvermoon, instead of a portal to Orgrimmar/Stormwind, your realms will see a portal to Exodar/Silvermoon - those cities as well as every other will have a portal room, an AH etc.
With the increased number of people from the cross server expansion, why not now make use of these cities as go to places for for realm groups
