So it seems my campaign might not be entirely gone just yet with Durthu. I went into the mountains as my last ditch effort to find some gold, and oh dear did I find some gold. The orcs up there were just coming back from what looked a failed raid on Bret lands so they had a bunch of wounded armies, I cut them off and killed most of them, then started razing everything. So much gold, best one was like 49k from one of their big fort. Then I rebuilt them with a 2nd cheap army I made with my new found gold, and started installing the outposts stuff. The casualty replacement one is stupidly strong, along with tech tree and one point in replenishment in the skill tree I basically heal my whole army like 60% per turn, so I can just keep razing and repopulating without almost any downtime. And once you're done with the region, you can destroy it and build the faction wide ones instead in one turn and like 100g, it's great.
I also like how efficient secondary armies are for Durthu, Ancient Treemen, the tree lords have really powerful army bonuses for other treekins(20%damage reduction and 10%weapon strength), combined with the basic melee tree buffs and 1pt in Lifebloom to get map wide constant small heals and you get a really potent tree army at very low cost(mostly dryads, a few treekins and a treeman, and maybe 2-3 gladeguards with starfire to take out annoying big stuff).
I guess I was too focused on the traditional campaign system of conquering stuff and building a steady income, when really the faction seems to be stronger played as a horde with a few buildings.
