It needs to be said as well that in the beginning of any world many alliances will start out as MRA's. Not a very good idea, but when you're trying to get a foundation right from the beginning, the leaders feel it's best to invite as many players as possible and then cull the herd once they have an idea as to who is active and who is going to be little more than dead weight. In this, of course, they take down their numbers. The problem with some, however, is that they are reluctant to kick out many of their members, feeling it will cause hurt feelings, bitterness, etc, and so they get stuck with the dead weight. And then, too, you have some leaders who try to get rid of the dead weight and they are blocked by their own council (such as happened to me in the world of Chi on the EN servers). From that point on, I swore to never play in an alliance with an academy, nor would I stay in one. Having been there and done that, knowing the chaos and confusion, the frustration that comes with it... I definitely won't do it again. Those who do...kudos to you and I wish you luck.
There's also the fact you have some alliances led by new players. Not noobs...as there's a difference between "newbs" and "noobs"...but new players who think starting out with a big alliance is a good thing. They soon realize that many of the experienced and the vets of this game often wait to see which alliances are worthy of joining.
