No doubt none of us are perfect. As you point out, I did not win W73. Actually there are a large multitude of worlds I do not win, I've played a lot of worlds in my time. If I had won every world I played, I'd be somewhere around 20 wins. Similarish situation to this world, AJ asked me to help out and I did. I can't say I did perfectly, but I transformed his tribe Joker from a family tribe like Jager which was going to implode within about 2-3 weeks to a force to be reckoned with. We won two wars with top 10 tribes, turned a 100 man mess into a 25 man team and became amongst the best in the world. We did this with local talent even though we were surrounded by premades on all sides.
I will admit it was a lapse in my own judgement to try lead two worlds at the same time. I was also leading SPAM on W60 and although I was baron in W73, I was essentially doing the majority of the work. I decided to put my focus onto finishing W60 which I had already dedicated several years to and merged my tribe into IKEA so someone else could take up the reins and essentially quit as soon as that decision was made. Yes it wasn't ideal, IKEA wasn't a very good tribe but then there wasn't really anyone to replace what I was doing. So yes I did quit and yes, due to the way front collapsed when I left, my villages started getting taken so it was my fault. I think if I had founded the tribe and played only one world, then I would have done a lot better, but the past is the past.
I've not been one to brush over my own mistakes, I don't mention past worlds because I find it is pointless to do so unless someone specifically mentions something untoward. I just find umbrage with that certain attitude of "leaders serve their members" because I've never seen it working out particularly well just as its own individual piece. No matter how hard you claim to want to serve your members, that only actually matters if they want to be served by you and are willing to follow your instructions which has come from the work that you have put in for them. To me, that attitude comes from someone who uses it as a member as an excuse not to follow their leadership. Because yes, when you need help a leader should help you, but it is your duty as a member to help the overall tribe, serving the rest of the memberbase and to make sure the work the leadership put in to serve you is not all for waste.
