I currently run CSM and I tend to play at point levels of 1850 / 2000 / 2250 and I tend to run 3 troop choices being 1 - 7 man nurgle and 2 - 8 man zerks. I have effectively won games with this small amount of troops and was wondering should I try to incorporate another troop choice and if so would adding say 7 lesser demons be enough? I am not to sure on what is an ideal number to run lesser demons. I plan on using them for objective grabbing but would also like to use them for tying a unit in combat to get a counter charge with my zerkers so they would have to be large enough to withstand one round of atacks. Any suggestions?
