Now I would agree to some extent but take it from the guy whose been in 16 clans, going from the existing ones like KSI,Die Hard Gaming, United extreme gaming, FEAR, and a lot more each one id give from 2 months to almost a year and each one is different but not a single one would give me exactly what I wanted.
Usually ill admit it was the people in it, so in making your own clan YOU choose whose in and you control how people act and what they do, this allows you (if successful) to make something that you'll enjoy.
