I hope they make other characters relevant again in the episodes after the new movie. Right now Goku, Vegeta and Frieza are so far ahead of everyone else that it's getting kinda boring. 17 is quite strong now too. But even guys like Gohan, Buu and Piccolo can't even compete with 1st form Frieza. They're probably 100s of times weaker than the main guys. Even Gotenks wouldn't be a match for 1st form Frieza now apparently.
The other guys need some buffs IMO. Otherwise all they get to do is do some lame ass filler fights like in the TOP. Even there they were only useful as filler because the writers didn't want the 10 guys or so who were actually strong to just KO everyone.
