What you should understand is that most people don't read the description. They just join the party. Maybe they didn't read it?

When I make a party, I put the strategies in the description and once we queue in, the first thing I get asked is are we using this or that strategy? I have to remind them of what the description said because they just don't read it.

I have asked who is flexing in P1S sometimes and then they just use the damage down strat or they all joined without knowing what flexing is.
