Balmung, in general, seems to be a heavy role play server. Its fairly common to see folks engaging one another in character just about everywhere. Add to that, I'm in Hyrist's RP/Endgame shell. They're good people. I'm also part of crystalline-rp.net, though they're more RP centric. Dark Embers would be a good shell to both have progression AND RPs mixed into once nice bundle. Kind of like a fast food value meal, only one that doesn't kill you (unless you order a Titan EXtra Large).
Balmung doesn't have restrictions on new players, per se, but at peak hours the server does close off character creation. Best time to make a new character on our server is off US peak hours, when the server isn't as populated. It'll be late into the night depending on time zone, but I assure you, it'll be worth it.
