It seems to be a well thought decision. Such a pitty that you have to leave, but I think you are one of the few charismatic and awesome members of this community who nobody would be bitching about if you would come back after a while. Some people vanish in the thin air all of a sudden and you never know the reason, but you bothered writing your reasons to leave and writing probably the best good bye post I have ever read. It's a shame I couldn't get to know you better considering everyone loves you here man, but you know, I'm not the kind of talkative person, but I can be a good listener if you want to talk.
I guess you were focused more on the social part of the game than the game itself. Always having fun with your fire truck spreading water all over the crowd making them to scream in impotent rage at their PC screens. lol If I remember well you were not a bad figher at all either, but you've always found better ways to have fun.
Take care man and let us know good news about you.
