1 key=1action does not refer to boxing it is any WoW player. As quoted from many WoW GMs if you use this rule you will not get banned. They can tell when you repeat keystrokes many times and they will talk to you in game. If you reply, they say ok but you know they are watching you closer. If you don't respond, you are considered a Bot and get a ban. Doing 1 thing on different toons with 1 key is allowed. Why would Blizzard stop you from playing more than one account at a time?
