Zenon said:The army regulars (mooks) are important to attack-
High level opponents WILL be brought back. No doubt about it. They will be Raised, Ressurected, etc. There's no way the Valloreans will leave that much experience and combat firepower go to waste. Assaults on the high level opponents will generate high-level losses on your side.
The Valorean's have been presented as fanatical do-gooders who are willing to die for their cause. I do not think death will cause moral problems. Moral problems will happen if you can get some Valorean leaders to defect.
As for the High level opponents and being raised and ressurected. Thats why its so important to take out the the high level Clerics. It will also be important to come up with ways to prevent True Ressurection. If you could get rid of all the Clerics able to cast 9th level spells they will be in a world of hurt.
