A couple of comments have said anyone who says cross-realm GW are enjoying their benefits too much to let go. Well I would have to say to a degree that's true.
Although I wouldn't want to lose my benefits, my concerns aren't just that. I'm considering the long term. Games such as these tend to end up with the big hitters in the top guilds/alliances/leagues. You can pretty much guarantee where the profit is, the top players are or will end up. This is by no means their fault it's just how games evolve. Ok currently on servers 1-10 there is a dominating guild in each realm. There are also at least 1 possibly 2 smaller guilds who may not have the city buffs but at least get to compete in Guild Wars for their assistant.
Merge the GW realms and these guilds will disappear. At least those smaller players get a chance as it currently is. As it's been noted, servers 11+ already have one dominant guild.
