Here's the thing - if they play solid, clear 100% of the map and managed diversity....yes, you're going to get smashed. You should assume though they are sitting in tier 13 because they have issues right now. Maybe poor diversity, players that don't bother to attack etcDon't count your alliance out in this war...play to win!
I'm guessing because y'all are fighting in tier13 probably not many gold alliances are in that tier
