which you cant use outside of narrative or open, at which point it doesnt matter as you can just smash any nurgle together and make it fairly good as it all synergies.
most of the characters from nurgle are so garbage you don't see them played. never seen orghotts on the table top in aos id forgotten he even existed tbh , seen morbidex twice, glottkin a few times simply more for model than rules, no one wants to buy 15 boxes of blightkings to make a army and slaves to darkness suck to add to them, with no rules in the gbh2 if they dont get a release they wont see play until 2018
