I have 3 units of 10 Daemonettes, 6 Fiends, an old Keeper, and a custom Herald of Slaanesh on mount, which looks to be enough for a Cohort of Slaanesh. Has anyone tried out the other Slaanesh units (the big lawnmowers, or Slaanesh Princes, or the Masque)? I'm wondering if a mono-Slaanesh army might be a good performer on the table top. Or maybe toss in mortals for the other half of a 2000 point game? I was disappointed in my Soul Grinder's performance at Adepticon, but maybe that was because I ran all Khorne for that event. Perhaps the Dark Prince is calling it? In general I don't see anyone using Slaanesh, except very very rarely in 40k, and sometimes in 30k.
