LoL you don't get one shot with a burn modifier. You get one shot with lightswitch AND arc burn. Beyond that even lightswitch alone won't one shot you. Also, you can easily run and gun all the NF's.. check youtube for speed runs there are loads of them. It's ignorance like this that I avoid by kicking campers.

How do you do Omnigul if you don't hide? I'd like to find a better way to get that crack ho without dying from that hordes she calls out...

Every boss is a NF can be easily melted with the proper strategy. For Omniwhore I like to have a WOL Titan drop a bubble on her platform. All three players proceed to unload their heavies followed up by Arc Shotguns. If done correctly she won't last more than 30 seconds. Thunderlord shreds her, Gally melts her. Shotties eat her alive. WOL will increase the damage on LMG's and Shotties not rockets so start with rockets, pop up a bubble and take away the last half of her health with shotties and LMG's (switch over from rockets).
