No, it doesn't outweigh anything. It just brings up the question WHY a large amount of users leave AFTER they earned the most valuable rank of all in terms of options/possibilities. I can tell you why: There's nothing more to come beside grinding for features you have on any other server anyway like water and lava placement without cooldown, you can grow Cactus, use hoppers, pistons, and anvils, have your little animal farm...that's the stuff you realize once you have the land to start something...I was dumb enough to pay for water, I really regret it now.
That looks like a good point, but... hoppers and pistons? Seriously? I totally miss them here but, AFAIK, those weren't locked to make a feature (like anvils): they are just totally and completely disabled because they create lag. How come other servers, maybe even more populated than our own, don't suffer extreme lag? Are you sure they are actually enabled elsewhere?
