Big Bannor armies are going to be fun. Donal Lugh has always had a lot of potential for generating very green troops (kill a measly skeleton, then use the Recruit ability in a big city, then look for another chump demon/undead to kill). Putting those green troops into a command structure where all kinds of "proximity buffs" come into effect (jacking up their combat strength, giving them %xp bonus for battles they do get into, etc.), very useful. Those green troops can pretty quickly end up Sergeants themselves, possibly just in time to adopt a bunch of what I'd call "privates" which Donal has generated in the meantime.
All this, and I haven't even tried out Crusade yet... *adds dozens of worthless demagogs to army, watches the buffs improve them*... hoo boy.
