I couple things to make this set viable
1.when it brings in items and you are full let them drop at your feet for your team to pick up.
2 Get rid of the random ammo on random weapon, make it simple like shock on 1 fire on 2 bleed on 3.
3. Let the ammo stack up to 30 and then extra fall to the ground for team to pick up.
These 3 things would make the set a blast to play and I dont think it would be OP you would still be way under powered on dps or ttk compared to a HE gear set.
