Rock Moveset and Attributes

You don’t even need to use s.HP in that situation, you can just run under Tiger Shots/Tiger Super and punish him.

I want to know more about Rock’s normals
Are his good pokes only low (c.mk, c.hk)?
What are his good whiffed-poke punishers?
What are the benefits of using his fierce or roundhouse up close (when not a sure hit/combo)? I see some people do it, but I don’t know why
Are his jumping punches worth using?

Also:
If I do a strong elbow at a further range, does it have the same recovery as a jab elbow?
Is Shift his only ‘cross-up’?
