First off, i'm not even in this clan but i used to be, so i'm going to say this.
Being 'bored' of something like vector should never be a reason to leave
You got bored of it, or you never really connected with anyone? It sounds more like there was no reason for you to stay anymore.
That happened with my old clan, mystic. It died out, and eventually I left. Same thing with Darwin. The leader left us and since he was the only person I really connected to, I left after awhile. I didn't really know anyone, and no one cared to know me. It didn't feel like a family, the way vector feels like a home to me
