You've got my sympathy, Assasin... I know how it feels. After gettin' my first taste of RDR, I couldn't play it for quite some time due to some unfortunate life complications.
Now that the Nords have been brutalized and lost nigh-half of their territories, I finally took note of their pleas for mercy and accepted the peace treaty. I would of continued ignoring it until they were no more had they not many fiefs in Vaegir territory, since had I continued on the path of conquering, every other country would attack us to curb our overzealous blitzkrieg, and I would easily lose the now-Nordic Reyvadin and Curaw to the Khergits and dwindling-but-standing Vaegir forces, among other castles.
So instead, with perfect timing as the Nords' peace treaty came up once more, I decided to ravage the Rhodoks. They're neighbors to both me and the Nords, whom I'll be ruining again very soon, and I do love Rhodok Sharpshooters; not to mention my court is already in a town that was originally their territory before the Nords took it (Veluca). They've only been at war with the Nords on a few occasions, so taking their towns was hell on my troops' numbers. Regardless, nigh-all of their towns now belong to the Templar Oligarchy. All that remains is Suno, which is poorly defended as is since it was my own town prior to my abandon of the Nords; and of course, I took 90% of my troops with me. The Nords have been struggling to take it back and then keep it since then, so the constant struggle and loss of it's garrison'l make it easy pickings. They still have a large amount of castles however, so the Rhodoks are far from defeated. Not that they stand a chance.
