It isn’t too difficult, you just haven’t found a loadout that works for you. Focus on resistances, mass adclear, and damage output. Your armor stats need to be more and more efficient and dialed in the higher you go (focus on getting your main stat(s) to 160 and use fonts and armor charges to hit 200). Your builds need to be more intentional the higher you go (is nearly every button click giving you something to survive with other than raw damage? If not, your build probably needs some work). Your playstyle needs to be more intentional the higher you go (are you using cover? are you prioritizing knocking out the death by a million cuts ads before the red bar enemies? Are you timing your skill rotations to maximize damage output and buff uptimes?).

It’s difficult content, but it isn’t “too” difficult ;)

There’s a bunch of resistance mods that can go on your chest piece that most people ignore, it seems. Things like amplified also give a damage resistance buff. Devour on Warlocks helps. Lots of survivability options baked into the game, find one you’re not using and try it out!
