Running a Siege with Undead Captains
What are your thoughts about running an all-undead siege? On one hand, you don't need to worry about your captains dying as you can just resurrect them through the army screen during the siege. Plus, you also get poison immunity which comes in really handy imo. On the other hand though, your captains are a bit vulnerable to fire. (Though I haven't seen it really affect my captains, don't know why)
Me personally; I have rose to about 700 Attack Rating in Nurnen just using my fully-undead army yesterday. I think it's kinda cool tbh, but I'm a little bit worried about the forts I'm going to encounter in time.
