I'm not sure it's actually that bad of a list. The reaver squad's a little bulky (in my mind), and the Trueborn are pretty easy KPs, but with a little tweaking, it could do pretty well!
You've got very good target saturation, and the redundancy is fantastic. no matter what the enemy takes down, you've got two more squads identical to fill the role. You lack a deathstar unit, like incubi, but I think that's ok.
are all the trueborn carrying blasters? the way your list is written, it implies that there's only one blaster per squad...if that's the case, why not bring 3x3 trueborn, with 3 SCs? that way, you can keep the venoms out of rapidfire range. Other than that...maybe 3 Night shields instead of flickerfields? it lets you hold the ravagers back...
I like it, it's potentially very deadly.
and 42? Is there something I've missed, or is it funny because it's "the answer" to "the question"?
