Sure, this should be fun...

(The ones I excluded were Freeza's alternate forms, Metal Coola, and the dragon form of Princess Oto/Six-Star Evil Dragon/the water Evil Dragon from GT)
Perhaps I was too harsh on Beers and Whis, but IMO they got stale really fast. I ADORED them in BOG, really liked them in ResF, liked them in the U6 tournament, then they just got... Really stale.
Also, I ranked Mai as if she's the character from the original manga/anime, even though her appearance in her icon is her Super variation.
I will voice these criticisms with your charcter choices, though: I think having both Baby and Baby Vegeta is unnecessary, since they are the same character, just in slightly different forms (IMO, equivalent to having Goku and Super Saiyan Goku as separate characters. Baby didn't incorporate Vegeta into his personality, he was just enslaving his body). Similarly, you have the water Evil Dragon in her Princess Oto form, and in her non-illusory dragon form, when she's the same character (which would be like having Bulma in two different costumes as different characters). You also have Metal Coola, despite him being the same character as Coola, who you also have.
I would also suggest cutting out the multiple forms of Freeza. His personality doesn't change from form-to-form like Cell does, so just have one.
Also, you only have one version of Mai, the one from Super. Despite having the same name and a similar appearance to her counterpart from the original manga and anime run, she is an entirely different character in every other respect, so I would suggest having both versions.
You're also missing Blue-haired Lunch.
The point of Dragon Ball is to enjoy it. Never lose sight of that.
