Just one question myself:
Will those troops you march to NA mainly consist out of Grey Order troops or wil it be manly DRZ troops?
Woops dont let the "NA to NA people- fu EU" guys know that :X
Here are three options for you consider:
A) Occitan got EU support and came through Hospitaller lands with a large army to attack
B) Occitan got EU support and came through the desert lands with a large army to attack
C) Occitan is using their NA assets like you are using to attack KUTT
I happen to own a desert front property and would have noticed a large army riding camels nearby, as would have Astralis, or Hero Party. Even Cavliers would have probably seen them coming that way. Considering, if true, the claims of Hospitalelrs getting sweet trade deals with EU, they would have probably noticed it to. Seeing as how not a single one of the parties I have mentioned has spoke up about such a noticeable army, you are left with Option C. In other words, bloo bloo bloo, you don't like surprise attacks when someone does the same thing that you have done.
