I have yet to encounter a Gobi that I couldnt beat. Now im not saying that just to be cocky, im just saying that even though he is good, its not like any noob can pick him up and dominate with him, which is what I consider OP. Maybe ill change my mind if I face a really good gobi player, or once most players learn to play him, but for now i think he is powerful, but not overpowered.
