Bro, where are your rock cutters? It's like you don't even want to bypass the injury roll entirely for 95% of units.
Also elites didn't add anything for us other than commanders (which we already had plenty of) and sub-faction bonuses which you should probably use as it's fairly easy to remember a faction wide passive bonus and it doesn't require any extra models.
Just run something like 3xacolyte fighters (2 saws and a cutter or 2 cutters and a saw), 2 aberrants (1 hammer, 1 pick), 2 basic metamorphs and a purestrain.
Hand flamers are a trap. 2 pts for a 6" d3 shot laspistol that autohits isn't worth the investment unless you're just burning leftover points and don't have enough for another dude or more useful gear.
