Considered going with 30 Daemonettes (same command as letters) instead of Nurglings (tweaking the Nurgle herald a bit to make the points work). Though, I’d have to buy all of them… so I went with the Nurglings. I figured, same number of wounds and equally hard to kill. Less attacks, granted, but still deadly due to poison. Plus Flesh to Stone on the Bloodletters or Nurglings could be interesting and make both tough to deal with. The Nurglings also provide some mobility. Plus Nurglings are just goofy…
I went with Life Magic. Daemons are a fairly elite army, so being able to bring models back is big. Plus increasing the toughness on the Bloodletters (or Nurglings) by 2 can be big, let alone by 4.
