Especially when they send you a nice whisper pouring their heart out on why they want you to join?
Like, as much as I want to support small to medium sized FC's, before I quit and came back. I was in the best/top FC of my entire data center. (of the data center I used to be in)
Once you been in a top FC for quite sometime, it's hard to go back to smaller ones with the same old tight knit people to socialize with and the limited amount of people to do content with. And a lot of smaller FC's tend to be ran by a couple (bf and gf, gf gf, bf bf, etc, married) which is already a no no for me. Because those are two people you gotta suck up to. But that's a story for another day.
Also smaller fcs are better for sprouts, who barely done any content.
