Luckily, Grotesques are terrihorrible, so there's no reason to pay for them unless you're a glutton for somewhat bland sculpts with terrible rules. The new Wracks are very nice, though I'm not sure if I want to pay GW 6.50 apiece to use them when my converted ones do the trick at the going rate of 2.45 per dude. I'm surprised the new Razorwing is only 41.50 each, that's pretty insane by GW standards, though I've been told the model is pretty small. Either way, it's actually cheaper to use RW instead of Ravagers, though Ravs are probably better overall point for point. I've heard some crying about the fact that the Void Raven still isn't on the table, but we made out fat with the RW IMO.
Too bad my new project is still more interesting atm . . .
