Ahahha awesome. BTW don't forget, nurgle has never been all that great at killing stuff, just not dying. Most games are objective based so not dying on objectives is the way to play to your strengths.
At the end of the last edition of the codex I did pretty well with a big unit of possessed and two lords with daemon weapons. Possessed aren't any good, nor can they effectively be used in a rhino. I think the Killy units are going to have to come from daemon allies now.
