From this Tom Brady radio blog i heard,
He rated some high tiers as Raiden (due to the speed of enhanced electric fly owing all projectiles and somewhat he's quick teleport), and I think Nightwolf was mentioned in the top 3. He did mention that sub zero was the top character, but to get there, you had to play really smart.
I think he mentioned that Kung Lao was a bit overrated, due to his big combos being situational, and that his spin and dive moves were highly punishable on block.
He also mentioned that the Shang Tsung the top tier according to the Prima Guide loses 8-2 to cyber sub zero, ala dive kick shenanigans.
Would be good to look into what actually makes a high tier in a mortal kombat game. We'll probably need to consider things like:
- Damage output with or without meter, with or without the corner, the bigger the damage the less mistakes your opponent can make
- Effectiveness of normals, specials, enhanced specials and X-Ray. I'm thinking Johnny Cage's X-Ray game changer.
More specifically to Mortal Kombat, one would need to consider the tools:
- Teleports
- Containment moves
- Projectile, and various zoning, often projectile spam
- Rush down moves
