kung lao is beatable... but just look at his tools... he will be top tier for a long time unless they nerf something...
i watched 2 tournaments yesterday, and the characters i saw were.... the most used were: smoke, kung lao, ermac, johnny cage, nightwolf and raiden --- sonya, kitana, kabal where used some, and then a couple ppl used like scorpion or jade for a match or 2, but got owned
kung lao won both tournaments -- the 2 grand finals matches were, kung lao vs kung lao -- and kung lao vs smoke
on both streams they were discussing tiers, and kung lao, smoke, ermac, raiden, johnny cage, nightwolf were all listed in their top tier, based on there moveset... both tournament streams said this, and the strategy guide says that as well
you just have to learn to deal with top tier characters... they are beatable... :-D just really strong characters
