Question(s) about the new 64 bit servers.

Hello there

So I've waited until the 64 servers came around to play. I sort of forgot about LOTRO due to life and remembered last night that the servers are probably out by now. And look at that they are. Wonderful!

Now, I'm based in EU so I guess an EU server is a good choice but I'm curious on whether if I should choose the RP server or the non RP one? I don't have plans on RP-ing atm but I do love making stories with my characters and maybe at some point in the future I would like to RP.

On the other side I also like to simply chill out and play solo and just quest about with some music blasting. Do you think RP is still the better choice? Also what's the difference in the player count between the two?
