If you play as a character that is 14-15 or something like that, You grow a beard over time and if you shave, You get like a mini game like art but with controls like biology. You need to hold down a button to shave the part you're hovering over. This way you can create styles if you down wanna shave it all so you can have for example a beard like Gurney.
Costume fighting style. Some like the wwe 2012 finishers but you make combos and stuff like that.
Energy drinks in shops. You keep it in your inventory. If you drink it when your character is tired at night you get 2 more hours to be awake.
Have bigger dorms.
Real time clock option.
More realistic females. I doubt most females fight by slapping and kneeing you. Give girls real fighting moves and make them stop being a coward.
Remove the "favorite-ism". I think when someone hits a girl it shouldn't give you a full trouble bar. I would love to see nerd's attacking a female jock ( not just female cheerleaders ) and just watch them getting beaten up by her.
Bigger cliques. That would solve members re appearing over and over. the cliques should be 20-30 ( or more! ).
More female members in the cliques.
Ability to threaten snitches until they stop
In gta 5 you'll be able to be friends with pedestrians from what i heard. You should be able to do the same in bully 2 with adults and students and give you a bonus for it like :
-be friend with a snitch and they wont snitch on you
-be friend with a clique leader and have an option to join.
Different paths and moral choices.
Have the dorms locked at night like beta.
Giant school. ( like hogwards from Harry potter except no magic of course. )
Maybe a tiny nose bleed on knocked out students? If a freaking nose bleed will be controversial i will lose the little faith in humanity i have left
Bigger map.
