Yes, it tells you that we are a group of top-heavy alliances which have primarily very strong mid and upper tiers.
If you wish to make fun of our lack of a large quantity of low-tier nations, then by all means by our guest - I'm quite sure we will not take offence to that.
There are indeed other factors, if it were just the raids, followed by an honest apology and speedy reps - all with good will, then we would not have done this.
However the situation is that this is not the first time RS has attacked a protectorate/ally of ours, and they have mocked us publicly assuming we will do nothing. AZTEC are very peaceful, we have no interest in starting wars, but we when someone like RS pushes us again and again, we must draw a line.
