How about some things that should have been in Brawl:
1. A roster bigger than a measly 35 with characters
2. The inclusion of characters who actually SHOULD have been in the game
3. The exclusion of characters who SHOULDN'T have been in the game
4. No adventure mode, or at least an adventure mode that didn't have awful gameplay, abysmal storyline, or one that is so focused on that it harmed every other aspect of the game
5. More Assist Trophies
4. For items to be fun again like they were in Melee
6. No tripping
7. More stages and better stages, including N64 stages
8. The DECLONING of characters from melee that DIDN'T happen
9. Different break the targets stage for each character
Biggest Thing:
10. Any kind of implication that they knew what DK fans wanted AT ALL. Diddy Kong is great but where was K Rool? The selection of music was abysmal! The only DKC2 song they chose was Stickerbush Symphony and they BUTCHERED IT, making it even more synthy than the original and completely changing the timing, god it was awful. Also, 2 stages labeled as DK and not a single one from DKC or DK64, the games DK fans actually LIKED? DK fans DON'T like DK for Jungle Beat or the classic arcade game. Thank god the 2 DK stages were revolved around those games.
Yeah overall, Brawl was a HUGE dissapointment, but it is still really fun.
