To me any time you are having a piece of hardware or software doing something for you that it outside the intended scope of a game, it is a form of cheating. Now setting up buttons to do combos for you isn't as bad as leaving a character online fighting for hours when you are not there, but it still is cheating IMO.
And Vanddelay, you sure could find better characters to buy than mine lol, or at least I'd hope so. Afterall, mine might come with some baggage.
