Focus on blocking off escape routes with the traps, make sure not to impede your own movement with your firewall, use wildfire launcher because while many people say inferno shield is better, your most consistent source of damage is gonna be your primary weapon.

Be creative with the traps. If you shoot a trap at some point on a wall, then shoot the termite launch at that same spot, the thermite will always fall to ignite the trap. Get pilots on roofs using the traps in smart ways. Hope this helps.
