I agree with the dude above, the low quantity of hexrifles we can bring makes them pretty useless. Those 55 points would get you another Kab Blaster squad which would do significantly more work.
Also, if you lose your Hemlock early due to good/bad rolls, you're boned against any amount of armor. You may want to consider scrapping the Grots/Talos for Lance or equivalents. Ravagers, Scourge, either of our flying vehicles are all good choices.
Yo ho, yo ho, a drug-fueled BDSM space-elf pirate's life for me!
Can I get a Roll Tide?
