That’s what happens when damage gets scaled up while health and shields stay the same.
It still baffles me that they didn’t bump up enemy damage along with their health in mayhem levels. It left this weird place we’re now in where one shot with a white splash weapon will hit harder than all of your health and shield combined. And self damage ignores health gate.
With Moze I’ve built her to take advantage of this with the double downer shield and the new blue guardian perks. I generally go into ffyl on purpose now since it lasts forever and I’m doing more damage that way. I only have to be careful I don’t do it too much or else the ffyl timer gets too short to survive.
Edit: For Iron Bear, unfortunately we are stuck with using hardpoints that don’t to self damage or be extra careful about what we are shooting. Sadly Auto Bear isn’t that smart and will kill itself instantly with the wrong skill setup. I’ve been really enjoying the hammerdown protocol. For some reason IB is immune to nukes.
