Isn't transfers to select servers free in WoW as well? I seem to remember it being so... Just that with a paid transfer you can transfer to any server you want, which it seems that Rift won't support.

Instead of server transfers, I think it would be really cool to be able to group with friends on other servers and hop into dungeons or warfronts with them. I have lots of friends on other servers but I don't want to transfer to their server. Especially since they may be playing on a server with different rule set (PvP / PvE / PvP-RP / PvE-RP).
