That's what I'm thinking of taking to an 1850 tournament in the near future. Using the 2
HQs to "abuse" Look Out, Sir! on the Warriors/Shrikes, Termagants to grab a backfield objective and the Hormies to throw a bajillion attacks into whatever I send them against.
I might have issues with AV14 but there aren't too many armies that can spam them in massive numbers (not in tournaments anyway), the Parasite can pen (depending on rolls) and I don't have to trade in the Doom's blast.
I first thought about a Nidzilla build, but I don't have the models ready and likely won't in time.
I might be called a heathen for not taking any Hive Guard but with the ease of glancing transports to death I figured all the Ymgarls would work for that.
