Regarding weapons, pistol, grenade, and heavy weapons are light blue to us. I myself am using a ql200 original electronium with a scope which deals some decent damage. I have a ql200 OT-12 which looks like a real nice gun for an eng to use except I don't want to ipr to test it. Shotguns are great guns to use now for any prof yet I forsee their use diminishing once they nerf crits.
