So I became intrigued with the new'palgue bomb' list and developed my own that I have played a few times. First the list ...

(12) Loota Boyz 180

(25) Grots, (2) Runtherd 95

(1) Dakkajet, (3) TL Supa Shoota, Fighta Ace 130

- 2000 -

Now the explanation ...
You use Aura of Despair toi kill off your grots and immediately reach your tally for Epidemius. Your troops are now enjoying a 3+ FNP and wounding on 2+. Just march them forward and watch what they kill. My warlord is given counter-charge. I originally had a much smaller Ork detachment. I also had a Meq as my HQ. It was suggested to me by a friend to try a warphead in a squad of lootas to shore up my AT/AA. THe is very little in a nurgle list that can shoot - well three breaths is all I have. I then added a dakkajet as it works well with my FMCs. Now the list has performed okay and is a blast to play but there are a few rules questions I've encountered. I actually posted them here for responses.
We have been playing that the Aura requires no target as nowhere does itt say it does - just LoS but there are a number of examples that follow this - thunderclap for one.
I'm not sure how warphead zzaaap works against flyers. We used needs a 6 to hit but really it is an automatic hit - so?
That aside it is a tough list to prepare for in 6ed. Yes, it is slow. But if you can keep Epidemius alive - and it is not that hard - you will be getting the tally on turn two/three generally. A bad wave does not help but it can be overcome.

So that's it. I cannot claim ownership of the original concept. But the list is changed from the original design - no herald, inclusion of FMCs, no screamers, larger and different Ork detachment.
