Generally speaking you are economically incentivized to spam cost effective ranged units and spellcasters that can wipe armies with AoE shit.Any recommendations for generating more income? I'm in about turn 48 of the Kislev campaign, I have about five trade routes set up, and I've been exploiting the diplomacy commands to demand payments from my surrounding allies, but it's still not enough. My two measly armies are still sucking up too many funds.
I think you can do fine with Kislev if you only use basic kossars in an army. They don't deal much damage on melee, but their melee defence is pretty high and it takes ages for them to rout. Put everything on a bit spaced out checkerboard formation so even if the enemy cuts through one unit they won't stop the entire backline from shooting. Similar thing works with all elven faction.
