i think you have missed these things. all throughout the forums people will say o no that sucks "hes not rooted" if you see some hopping or "he has no structure" when referring to seeing a person turn their body to punch. this is peppered throughout the forums.
i met people in person that tell me they dont fully extend their arm when they punch, or that they never take their feet off the ground so that they stay "rooted".
i meet people who keep close to 100% on their back leg, back is completely straight. yeah sure they have some footwork. im sure they think its good. to me i say that is too stationary and too stiff.

of course this is just my opinion and i am expressing it.
