So far, for me, it has to be the Badass Pyre Threshers that frigging take you from full life to near dead when they first come out and just seem to eat the damage.
The next worst for me has to be the Rabbid Skags. Those things are worse than most bosses. Really sucks when you get jumped by 3 rabbid skags at one time.
On Op8 so far, my biggest nuisance has to be vehicles though, going through the Badass Crater at Op8 and those motorcycles are just insane compared to my vehicles. Have gone from full health to my vehicle exploding within 3 seconds from them, if my truck hits one of them, they take a little damage while my truck’s health bar is flashing danger. And if they hit you outside of a vehicle, they almost kill you as well. They really need to scale vehicles up properly for them.
Off-topic question, Does anyone else have an issue where your damage output drops when you go down into Fight For Your Life? I just don’t get it, I can be at point blank range against an enemy and it is like the second I go down part of the time, while I am down my damage drops by like 66% where what would normally do a decent hit of damage on them is now so low it has trouble keeping up with their natural regen on Op8. It isn’t every time though but is surprisingly common. Anyone else have this issue or know why it happens? And I know it isn’t because of accuracy because I have had it happen while at point blank range from them where it would take a conscious effort to even miss and it happens.
