The reasoning for your decline was just as said before, at that point we had just recruited a new rogue and we were full 3 rogues in the "core". The newly accepted rogue left almost immediately and thus we were in need of another rogue again. Also some unforseen events happened to me which lead to me being inactive for an uncertain time, so we needed to fill up the core again.
We don't just go by application nor performance. We look at personality and other fitting qualities aswell. I guess it's great that you could outperform our rogue team and I hope you find a guild that can suit your needs. But then again a last sentence statement like that also tells us something about your personality does it not? So I can see my decision was the right one.
Hopefully you learned something!
There will be no more replies from me.
