Not sure if that would be possible of if that's solely built in rust AI. Even the elite crates if you have any distance you can pick em off one at a time since only the one you hit will return fire. If it were possible to have an option that when one gets hit they all return fire that would definitely go some way to reducing the cheese I think.

Also is the roam how far they will follow you, or is that for their behavior just at the crate because mine just are at the crate and stand still until they either see you or you tag one of them.

I totally agree with this. Right now they stand around and can easily be picked off. Can anything be done about this? If you're close, they're relentless but from a distance they stand around and get picked off.

I also think it would be a great addition to the behaviour , not sure if its possible though as i have not seen this behaviour in any other bot plugin ,
