I really like to play it safe. I don't want to rush Kung Lao to much because of his spin. Sometimes his EX Teleport throws me off. I'll try to rush Kung Lao a bit more.For Kung Lao, its pretty much a rushdown race. Get in his face more than he gets in your face, and then let your combos do the talking. After a knockdown, bait those wake-up Spins (which are stupid easy to punish nowadays), rinse and repeat. the problem starts when he's a bit away from u, because he can pepper you with Ground Hats and annoy you with Dive Kicks, but getting in with a quick EX Flying Kick would remedy that nicely. I personally don't find Kung Lao very difficult.
For Ermac, you just gotta stuff him. His wake up game is horrendous, because baiting those Force Lifts and/or teleports and blocking them just makes Ermac bend over and say COMBO ME. Mix it up with for overheads, and the usual low poke combo, and he'll be flustered. Just don't be too offense-oriented, because if you do get hit, it's usually 40-45% of your health gone.
It's going to be awhile before I adapt to beating Ermac.(One, because I don't play him often.)
Thanks for the help people.
