FYI: Just found out PS+ Max of 2 PS3s can be active. I got, in different areas of the house, the fat, the slim and just added the Super Slim. Sony won't let me have a 3rd on PS+ Hope it lets me play online!
PC playing allows you to run as many accounts as your computer can handle. I run around WOW with four characters at the same time. You should upgrade.
What do you do with 4 chars? Are macros so advanced now that you can have your own bots in your party? Or are you actually controlling all four?
I always enjoyed world PvP more than anything. One major reason the game was ruined for me beginning in late WotLK, when that dungeon finder crap was introduced.
