Eh? stLP, crLP, crMP, and crLK are all +1 or better normals. Hell, stHP is 0 on block. At +1 you can't even challenge him with your own lights because his bMP will always beat them unless hitboxes get in the way.
And listing Necalli in that bunch of better pokes...ehhhhhh, not even being a Necalli boy, but his buttons are probably the weakest part of the character and lack behind quite a few characters generally. Ken's buttons aren't as strong as some of those characters, but when they land, he gets really good rewards, and it's not like he can't play around them anyway. Normals are only one aspect of it anyway.
