I'm interested to know what everyones opinion is of cross-server gaming. For those who don't know, some MMO's like World Of Warcraft have introduced a feature that allows you to party with players from other servers in an effort to help reduce the time you spend waiting in an instance queue. It also greatly increases the pool of players who could be looking to do the same thing you want to.
One of the criticisms however is that it harms the local server community. Players tend not to try to get to know other players outside of their guild, or even remember them because almost every time you do something you are doing it with different people.
So which would you rather? A server community where after a period of time a lot of people get to know each other, including those of other factions. Or a cross-server setup that allows for a greater pool of players to search for when trying to participate in instanced events such as dungeons or PvP.
