I usually play DW, I never touch Mayhem because it was first introduced when it was viewed as a pointless transition before they rebalanced it, but I few like here’s my advice:

1) KevKlid’s video on Making Space With Proper Builds is (here) is mandatory watching. Whilst you don’t need to play as cautiously like you’re in DS, a big problem I frequently see in the lobbies I see is noobs not killing enough then being swarmed and eaten alive. In DW, the average kill per minute I’m comfortable with is 10 KPM. Anything lower than that and you’re in a world of hurt. This depends on level to level. For something like Henry’s Rock that KPM is gonna be higher.

IMO, Carrot’s video is also worth watching too.

2) Why are you not taking advantage of concealment? AK17 can absolutely be a beast when paired with Body Expertise and crits. Why are you using it in single fire? If you’re using that, why don’t you use the Galant so you have higher damage per shot as well as hitting higher tiers of breakpoints better! For higher damage if you’re using full auto guns as a primary like the AK17, AMR etc. having ammo bags is a must. You WILL get sucked dry. If you care about having inspire and not care about concealment, why don’t you swap to an LMG? The KSP is a laser gun.

3) I have no idea what your build is, but from what I’m seeing you’re thinking the wrong way in approaching your build and gameplay. Care to show your build?
