I don't know, it just seems like it would be cool to be the big badass villain fighting off the entire ESF team by yourself, like Vegeta vs Goku/Krillin/Gohan, Frieza vs. Goku/Vegeta/Krillin/Gohan, or Perfect Cell vs. Goku, Gohan, Trunks, Vegeta, Picollo, Tien, Yamcha, Krillin... well you get the idea. Of course you'd have to scale the power levels a little bit more like they were on the show, so that the lower PL characters wouldn't be too useful, and make it so only the higher PL characters could engage in melee. It would be nice reenacting that whole Cell vs. Gohan at SSj2 scene with all the little guys shooting him in the back. Mmmm...
(And you know Cell would have won if everybody wasn't nailing him in the back of his head. Vegeta was the significant distraction)
