Nice to see Daemons in 'ard boyz. I like my daemon army. I run Epi army up to 1800 then after that I have to add in other gods units to get to 2500.
The thing I like about it is that it IS more random and luck based than just putting stuff out and moving around and shooting.
I think objective missions are a forte` of the army. You can
DS on top of or near the objectives.
KP missions can hurt Daemons if your reserves aren't going your way, then again Epi-Nurgle is a very good
KP denial army. Excepting terminators and pricey Vanguard not much is going to kill 14 plaguebearers in cover all that fast.
