I wouldn't say that. The majority of the group has been entirely inactive for a while now, and if anything, I'd say you were more active than most at the moment. We're slowly trying to get things started up again, though, and we're actually trying to do an event pretty soon. I think the reason nobody noticed the comment was that most of the group wasn't even getting on Myriad for a while. If you really feel like you weren't contributing enough to stay, then we can't stop you from leaving, but personally, I think you were doing plenty, considering how much everyone else was doing.
Also, you're characters are awesome and I don't want them to be missing from the roster.
