So i'm looking at running a block of 20 marauders with LA / shields / command as a center piece of my army (with a sorcerer in there). The two options I was looking at was either having mark of slaanesh on the unit and a regular level 2 nurgle sorc. on a steed, or running the block with mark of tzeentch with festus in there. The second option would give me a 5+/6+/5+ save, which is pretty sweet for a block of marauders. I could also run the marauders with mark of slaanesh with festus in there to get a 5+/5+. What are peoples opinions?
