That's why FC's based static tend to be (not always, but most of the time) a drama pool. I know this may sound counter-intuitive, but the best statics I have tend to be a collection of 8 strangers. We tested each others, confirm that we have same goal, drive, and skill level. We don't talk much outside of raid, but most of the time we respect each other times, and that means showing up on time, pull your weight, study the fight on your own ...etc... If someone don't show that respect, then it's usually a pretty cut and dry case of removal. Go to most Static Recruitment posts on Reddit or Discord and you'll see most group post those same requirement.

The problem with forming static with people you know well, or "too" well, is they tend to think because of the familiarity, they can "slack" without consequence. Kinda how in real life, you love your family, you like to hang around and such, but if you gonna put resource out to run a professional business, then the same family members tend to be the worst employees. It's much better to actually hire "professional" who actively looking for the job, and aware of the afford required to retain that job without any kind of familiar entitlement.
