And I do believe it is likely there will be a server merge/cleanup after the launch, because the worlds are not fun if warzones pop ever 30 min and then close down in 90 seconds for not enough players.
This is happening all ready, but till all invites go out, its hard to say which servers will not make it.
Its easy to spot the ones that will make it, like The Harbinger, or The Fatboy, and Jung Ma. Those servers have a nice population and warzones pop all most instantly.
I made a char on day one on a server that didnt grow, though people keep saying they think it will once all the guilds are in, so I am thinking about starting on a new server today as well.
