help getting a friend into legion

Well the starter box is pretty good place to start as long as you're willing to proxy the Shredders as Mekanoshredders. Kryssa was always a fun warlock and the CID can only make her better.

Just throwing something together, I got this:
Seraph and Mekanoshredder can add 4" threat to your Neraphs, or if you Fury isn't an issue, a Warlord if you drop the Forsaken and a Shepherd, both of which can do work under Kryssa's feat and, hopefully, ignite post-CID.

To go in a different direction, here's a Primal Terrors list with Ogrun that can be built from the old Mk2 Two Player Box. Assault lets the Ogrun threaten greater than one might expect. Ogrun didn't get touched so they should be a stable suggestion.
