Aurvandil has a gold income of over 8,000 Gold, Aurvandil has the most nobles on any realm on Dwilight, Aurvandil has some of the best Special Forces, and the best Infantry. Did I also mention Aurvandil is arguably one of the best realms for efficiently distributing gold? With a heavily ingrained culture of collecting gold, requesting gold, and handing out gold. These aren't weird figures. This isn't anything not to be expected. What do you get when a very wealth realm, with a lot of nobles, and a lot of awesome recruitment centres go to war? A massive military build up, both in mobile and militia forces. And only weeks before the war, what happened? The paused character clean up, which gave every ruler a massive jump of gold, in Aurvandil it was 5,000 Gold. So not only did we have a large weekly income, but a massive boost from the paused character bonds, add this to a high level of efficiency, and you get a very strong military.
I don't see why this issue needs to be brought up again when it's been previously investigated, some of the potential wrong doers were removed and it was concluded that everything Aurvandil was doing, was reasonably within the game limits, no exploitations, and no abuse.
