Darius ground pound is the cheapest move in the game. If someone plays as this guy you can expect a cheap ass match. All they do is sit back and ground pound or throw a projectile here and there to make sure you don't keep jumping. I don't know what they were thinking when they put a character like that in the game. The best wasy to beat him is get a fast character and just stay on top of him. I prefer Lui Kang or Nigthwolf for that cheeseball character.
Raiden's teleport is easy to get rid. All you gotta do is duck or if he keeps throwing out a combo after teleport just dodge or block, then whoop his ass. Raidens got a few low high moves and can be difficult to read but I can usually take him out.
Nightwolf can be very cheesy. He's got that lightning which by itself isn't to bad. You just gotta keep moving to the side and be ready to block his dash. He's also got a variety of low combos and over head kicks which can mess a person up. I have personally mastered Nightwolf just for those cheese ass morons that piss me off.
Baraka is so easy to read it's not even funny. I don't know why people call him cheesy. Just block his stupid specials and whoop his ass.
