I get it now! I understood that all along! I'm still just plain missing a piece o mai pie I guess. I may just try and hardcode the vectors, instead of get the vectors from velocity by aim. This would enforce consistancy. Thats really all I want, consistancy in the way my hero is firing. I will do a diagram to 'splain.
As you can see from the pic, when you shoot east the front and back missiles get skewed, they get dramatically closer to you. The only reason I give a shit about velocity is because I am trying to control these four shots with greater precision and control.
