Anyone see the episode where vegeta went off on Frieza? It was more like Rezoku with generic beams. THAT is what Rezoku should be like, and not just some pansy ass 6 shot, you should be able to charge that bad boy up to like 15 or 20, but it should knock your ki out....that would truly make it like the real Vegeta...go-for-broke gameplay, but if he doesn't kill you, he is screwed.
Blade that is crap, Ive probably laid about 40 or so scattershots in the air at the same time, I never saw a lag spike. You might be referring to FPS drops, but if your fps drops from sprites you probably arent doing to well with the rest of the game either.
