i have just resubbed as well. Seems to be a lot more people around than when i first started, altho thats probaby down to the ftp and also server mergers. Im having a great time with it again, and glad i came back.
I share this sentiment completely. Somehow, the game feels more 'alive' then it did back when it was P2P.
I deleted all my high level characters (cuz I couldn't get back in the flow of things), moved all my credits to a new character and went to town on some Legacy perks. Even the starter areas seem very active. That was a pleasant surprise, because I didn't expect that.
The one problem I'm having is finding a decent and friendly casual guild since my previous guild dissolved into nothingness.
