My problems and hopeful fixes:
Buff the carbine and Br to make it on par with the dmr.
Nerf the boltshot. Make it more mailer like.
Reduce flinching
Make constant weapon drops and none of these random location/weapon drop.
Make it so that I can tell where my teammate died and if they are shooting or being shot at
Make the scattershot more predictable
Smaller maps
Allow flag dropping and remove instant pickups across all objective gametypes
Remove instant respawn
Make a lot of the perks standard abilities across for everyone (I think that this would fix most of my problems. Weapon drops and location would be know, ability to pick up Andes, reduced flinching, ...)
