Chaos warriors stand to act as the tier of enemy above shield stormvermin with a damningly large health bar. However in Legend, even with the recent update, I’ve still noticed excessive amounts of chaos warriors not spread out along the map, but rather waiting all in specific zones just to wipe everyone.
What doesn’t help is that the chaos warriors will clip over one another, creating a wall of never-ending overhead swings. That and the issue with patrols spawning out of thin air or bugging out.
You can cry ‘git gud’ but there is a difference between something being an enjoyable challenge and being a frustrating conflict of pure rng with the AI director.
Even with specific armor-piercing weapons, it becomes near impossible to take care of the wall of 6-10 chaos warriors clipping in and out of each other spamming never-ending attacks on top of whatever else, if anything, you have to deal with (specials, hordes, bosses, etc.)
Edit: To emphasize, the main issue with them is the patrols on Legend. They are basically a wipe unless you have a few miles of space to kite.
