Sure, right. not cheating technically, only because it is allowed. For what reasons it is allowed I'm not sure, but I can tell you that it is damn bullshit. Hey lets take out this one feature from game which kept the playing field somewhat level, and then we just allow whoever wants to have unfair advantage ability to use it.
Regardless of whatever bullshit people use to justify use of FR and Multibox, it doesn't matter. In the end they are still just a loser, with no values or self respect.
