BF 2015's Supremacy shouldn't include heroes at all. Vehicles spawn on the map and each team only gets one hero that can't regenerate their health, once that hero dies, no one else gets to play as a hero. Walker Assault should include pickups like thermal imploder and orbital strike. Then, add Battlefront 2015's Supremacy, which is nothing like Battlefront 2's by the way.

Every base trooper class gets a secondary weapon, of course with no cool down. The Engineer's ammo device only increases their blasters' cooling power. Heroes and super soldiers only cool their blasters. Officers hand out a single medpac that grants the player who received it 30 health, then it goes on a cool down. Heavies can hand out a single power pack before the ability needs a cool down. Engineers use detpacks, ammo droids, and can repair vehicles, turrets, and special weapons like blaster cannons and AA guns. You should be able to pick up a little ammo from fallen enemies, collect it from an engineer's gonk droid, or receive it from the heavy class. Players can choose whether it's worth it to give themselves a fresh magazine with full ammo, or time a quicker cool, but an emptier magazine.

Blasters with high capacity power packs and pistols with 50 shots in a single power pack overheat after long sustained fire. I'd like to see ammo and overheating co-exist. No spammy health buff and damage reduction abilities that that mess up the time to kill.
