Let's see...
GataKiriBa was used when a swarm of piranha yummy were pouring out of a building. It would of been real smart to take your time and test out all your options while piranha's are ripping peoples faces off.
RaToraTa and SaGoZo were used in fights against 2 Greeeds. We've seen him struggle to fight one of them. We've seen Yummies best him at times so taking your time while people are trying to rip your throat out is definitely a good idea.
This isn't a game. He can play around and experiment with combo's when fighting Yummies maybe but there are times when you can't take chances. You know cause if he dies the the world if fucked!
[HIDE]And if that's not a good enough answer then.
More times they show forms = Higher chances kids buy toys. That's the sad truth.
Stop over analyzing the children show. Eiji is not some kind of masochist that is getting addicted to the main forms. :redface2:
