Alright so in IoQ you usually never have all 3 people on the turrets so when seige is at the door your all alone. If you fire your napalm and the seige and swap to the next turret you can napalm again! up to the 3 turrets right next to you. The cooldowns follow the turrets not you so you cant swap infinatly many times but thrice which will add up to 4.5k dps just from 3 instant shots. happy defending!
