It's not about account being blocked. I dont know if any of you guys tried, but that's like trying to connect to the same account from 2 different computers, and thats not possible, since the one is running gets disconected when you open it in another computer (we have 2 comps at home and i tried).
But i guess that it is ok to run 2 different accounts in the same computer, and nobody can stop you from doing that. Even if they check the IP that is conected they can not do anything. My bf and I play GW from the same IP but we have different comps and accounts.
I think this may be interesting to start running my chars with his account since he is not playing it anymore...
hehehe
