I tried both systems, and I liked that I did not have to wait for an officer to be online to invite an alt in if you join a guild with your account. Whichever Character you happen to be playing will apear in your guild roster. You can join multiple guilds in this system, and then pick which one you are choosing to represent at the moment. However in GW2 you do appear online and not representing in the other guilds roster unless you log in as invisible I think. what do you all think about joining a guild with your account? pros/cons?
