It's impossible to prove, but if you put the round 55 roster against any kingdom in the history of utopia, we would win every single time. Then if you factor in that we had to B2B2B 3 allied kds and win by over 100k land, it makes it even more impressive. That roster was stacked with legends.
ABA, I'm taking it a step further and saying all time.
We should have a war versus server for fun where you sign up 2 kingdoms of 25 people and give them X land to explore and they fight in 3 weeks.
