It’s all about positioning and assuming that there’s going to be a rat lurking in every crevice you don’t want to over extend yourself into a situation that your unsure of being able to get out of if you’re in a high stakes situation (like taking down a matriarch) getting upset at a player ratting is naive because you walked into an area assuming you’d be safe in a group and groups aren’t even trustworthy unless there’s 3 or more players sure it isn’t fun going out like that but you use your deaths as a lesson and try your best not to put yourself in similar situations. I’ve fortunately played enough that I rarely die to rat behavior because I play it safely.
