Astounding job especially in such a small space of time. Quite the look I always think of when regarding nurgle. I dislike the generic green.
Care to share how you painted them thus? 
Thanks for the compliments! I have never particularly liked the generic green, as I don't find it particularly representative of plague and disease.
I am more than happy to share how I painted them
I don't have the colour names to hand, but I will work with the names of the new range...
I started off by solidly undercoating the models in white. I tried doing this with a brush at first, but actually found that a can of white undercoat gave a thinner and more solid coat.
Once these had dried, I then applied a liberal wash of Reikland Fleshshade (Ogryn Flesh).
Then, I applied Biel-Tan Green (Thraka Green) wash, but only is certain areas, and only 5 or 6 patches on the whole model, giving the skin a mottled appearance. Really try not to go overboard with this, and each patch should be really quite weak. Water the Shade down if needed.
Next, I used Seraphim Sepia (Gryphonne Sepia), and just gave a mdeium wash to the model, focussing on the grooves and recesses, but leaving the majority of the model untouched.
Now, the sores, open wounds and entrails were the fun part. I would highly recommend buying some Tamiya Clear Red, as it is truly a God send for gore and gruesomeness. I carefully, but liberally applied this to all sores and wounds. With one coat it looks like it is a little bloody and sore, but if you apply a second, it looks wet, bloody and gruesome. The key to this stuff, is waiting until each coat is dry, as it is tacky and viscous, and can really make a mess of models if you are impatient.
Lastly, I painted the sword jet black. Try to get a thin, but solid coat, so that the sword keeps it's edges and detail, but is a consistent colour all over. Shades and highlights aren't necessary, as I then applied a gloss varnish to the sword, to give it the Obsidian finish I was looking for.
Base as appropriate
I would definitely say, that the two key points are to undercoat in white, and to stay away from heavily pigmented paints (hence the sole use of Washes/Shades). This way, you can achieve a disease-ridden, washed out skin tone, all in 5 minutes per model.
I can try and get a step-by-step with pictures together if you need anymore detail?

After all, painting 100 night goblins is something you do in the morning just before you are off to work.
And I think you missed a 0 when you wrote 11 armies. The correct nr should be 110 armies I would think, based on your painting speed.
keep it up!
Sounds tedious.
