Yea, Stryker was one of the first characters I learned because of his easy Juggles. It is not hard at all to get 60%+ after popup. Especially offline.
Though I also never liked Stryker growing up, or cared anything about him at all because he is a very dull bland looking character that wasn't even complete untill umk3 came out. He's a cop who has a fucking hat on backwards, how shitty can he get.
Kung Lao imo hehe... or stryker is good next option. I think I'm gonna put in alot of effort to learn sonya or jax next myself, since I never really played those 2 alot.
Im not to sure why you would ask someone else's oppinion towards a learning a character when eventually you will learn them all, its not hard to learn them all at once why don't u got alphabetically?
