I really disliked the models at first, too, especially compared to the 4e metal Daemonette models. Still, though, these ones have... grown on me. I guess there's a Stockholm Syndrome component to assembling 60 (75?) of the things.
I tend to see light Slaaneshi and dark Nurgle models, so I'm trying to flip the tables around with my own Daemons models. Going for a possibly slightly more typical dark bloody Khornate, but at least my Tzeentchi are going to be mostly green, rather than blue or pink.
...in other words, a riotous panoply of color and confusion. The Chaos Gods wouldn't want it any other way...
What sphinx of plascrete and adamantium bashed open their skulls and ate up their brains and imagination? Imperator! Imperator!
