4 Gohans and 4 Picos isn't exactly a fair counting. Not that I'm against them, thats cool. But to say thats 11 is probably a false marketing.
Also, Cell Max sucks. Super boring villain in the movie.
I still find it hilarious that of all the fights, the only ones that gave me trouble were great ape vegeta, fighting all the ginyus in one match, and having to beat freeza (form 3) in a very small window of time
This is dbz games in a nutshell, and frankly i think its fair game, each form have different supers/ultimates and depending in the character different combos (ie: imperfect cell plays nothing like perfect cell)
