From what I know, it was possible for you to buy the CS currency with gold earned in game allowing you to (eventually) buy your own runes and all that lovely stuff that turns you into a well oiled killing machine, however with the game itself transfered to a new host I'm not too sure if this is possible anymore? It doesn't matter too much if it isn't but I can afford to get myself runes if I'd like or to go onto the P2P server and enjoy the benefits there.
I'd also like to know if there are things I can do on the P2P server that aren't available on the F2P server, mostly out of curiousity since there aren't going to be such things as strongboxes, mounts, runes and other stuff.
