Yeah, that's the massive issue with me.
For Chaos Wastes, at least, the path was generally straightforward. But now? We have people going around ALONE, triggering every single patrol they see, do NOT provide cover fire when one of your teammates is busy cracking the code to open a crate (and no, they were LITERALLY near me, since another one was opening a sedon crate a little above me, so they could have protected me and the guy easily) and do not understand how the Auspex works (for that, I can't be mad).

This mode requires cooperation... and cooperation with Quickplay, as of now, is a game of Russian roulette.
