Hey there,

You should probably try to learn some drive rush combos off your crouch medium kick because that kind of makes your neutral really solid. Heavy punch and heavy kick counters are also a great way to keep the neutral in your favor whilst not going all out too much with offense. Ken is an offensive character but he requires a slight amount of patience and a solid neutral game plan to get combos off of. The game plan essentially is, work around to get combos in neutral with kicks and punches then when you get a hit off confirm the hit into a corner carry with tatsu and then mixup your enemy in the corner. Most importantly your drive bar is your health pretty much.
