The pink horrors have changed quite a bit since the last edition. Their saves are weaker (5+, but re-roll 1's) and their shooting is no longer assault 3 -- rather, they are a brotherhood of sorcerers with access to the change discipline. They are, however, quite cheap. And that is perhaps their strongest appeal. But that has to be weighed up against the fact plaguebearers cost the same (and are hardier), as do daemonettes (and are better in close combat). Even if the primaris Tzeentch power is okay, this is truly not a strong shooting unit any longer.
The best use I can think for them is as a screen for a herald. Indeed, a herald of Tzeentch is about the only reason that I'm going to field my horrors any longer. The instrument is fine, and the icon is welcome. The retaliation wounds from the blue horrors arising is okay (but a bit meh). Take a lesser reward hoping that you get a shooting (2 in 6 chance) attack if you like. But don't worry about them otherwise I think.
Here's a few builds:
18 Pink Horrors of Tzeentch, with an iridescent horror that has 1 lesser reward, instrument of chaos, icon of chaos upgraded to blasted standard, (207 points)
Fluffy (because its a multiple of 9!) and fully upgraded. They get 3 warp charges per turn and are otherwise completely expendable. That's probably why you're not going to take them!
10 Pink Horrors of Tzeentch (90 points)
Seriously: they're a cheap screen. Use them as such.
