It's really disappointing to see how many people don't understand this character on a fundamental level. Yes, he can kill in a hit. Yes he has the best 50/50 in the game. Yes he has an amazing poke now to compliment the only hole in his game.
What you people don't understand is, HE DOES NOT HAVE ARMOUR. Well I mean he has armour but it's pretty bad armour. How could this character ever be OP without armour? While he may be decent he's still in need of fixes, Skydrop needs to be about 20 frames faster on start-up and launch, putting it on par with some of the other overhead armoured combo starters. It also REALLY needs to be made safer, Sub-Zeros overhead armour is -10 on block, Quan Chi is -18? Seriously, and you guys complain about him? Learn to abuse your block infinites guys as it stands Quan Chi is one of the easier characters to beat in the game, you can just cheese him out by playing offensively, every time he blocks anything you do don't worry about those negative frames, just go straight into something else because his armour is crap therefor he can do nothing. LEVEL UP AND ADAPT.
