I still use the CE, it is no way as reliable in warcry 2.0 as it was in 1.0 but I still think it has its place in the Warband.
I’ve messed around with a few set ups. I’m currently running - 1 CE, 3 fiends, 4 daemonettes.
There are a few variants you can use like taking a blissbringer (fiend hero) instead. Or drop fiends for higher numbers or daemonettes.
I haven’t done much research on the infernal enrapturess but I think the 6” debuff ability is significant. However it’s only useful if a brawl kicks off with numerous fighters and that’s not really the way to play Slaanesh in my opinion. They’re not particularly fighty so you should avoid the meat grinder fights.
