1. Main suggestion: As you reach a certain level of xp (ex, 10, 15, 20) your main loadout changes from a lesser to a greater set of weapons. This would be very helpful

2. A system to place ammo in certain spots of the map (much like you did with the guns)

3. Prevention of spawn killings instantly and an autobalance system.

EDIT: Found a bug when new players join
