Personally, I think the asymmetrical programming from Gill of SF3 should've been the standard for modern day mugen chars since his release.
Why? Most characters aren't asymmetrical. Why would you waste time making something standard that's only going to apply to a few characters?
Oh, why must I tell 'em again?
What must I tell 'em, my friend?
That we are born into sin
And we are worshiping murderers
Nothing but evil duplicitous men
I know you heard of 'em all
We should just murder 'em all
We should just murder and ball
We dance on the ruins we looting from all of they palace's walls
