Well, you will won a lot if againts a low experienced player, but usually you will be easily beaten by more experienced players, and you said it's mushu, pretty easy to avoid rusher with that low gravity.
If you can, stop rushing, it's pretty bad for your improvement. I found that usually rusher kinda lack of action after the couples of the turns, for example like lack of comeback, confused and messed up when the rush attack failed etc.
