Scorpion is definitely NOT overpowered, he is about high mid-tier, according to Tom Brady (if you dont know who that is, find out).
he has several tools that give him an ADVANTAGE over many characters but his gameplay style is "Risk and Reward". havent you noticed that blocking his teleport/spear lands you a free combo? or maybe your skills need a bit of refining hmm?
TB does not make his Tierlists based on Online play... and online, scoripion is kinda like Overpowered. You cant do shit against his moves, same to Smoke and Cyrax.
