I am sorry wut? You totally took what I said completely wrong. I said regarding leveling and exping you brought in the WoW auction house? Enough with the merchanting thing, I don't care and to be honest, it isn't going to prevent scamming, news flash as you would say, people will still get scammed, even with two clients, in-fact, it may just make it easier! Pretend to be some other person, impersonation, pretend to be a trusted middleman, lol.. I mean come on now two. You really don't believe multi client will prevent scamming.
There isn't much of an advantage to other players with two clients? lolwut.
It's an idiotic idea, fair and simple. It isn't going to fix anything, nor is it going to better anything. While yes, np transferring will still happen? But with your route? Just make it easier for em, allow em to run two clients! Wewt!
