I'm curious to hear what people think about kill team setups and army lists.
I've found that my results when playing have been extremely varied. I have only played a handful games atm, a couple of 2v2s and some 1-1.5k games. I'll share some of what I've been doing and perhaps people can fill in with what I might be doing right/wrong.
Some of the different kill teams I've fooled around have been:
boltgun + power sword
shotgun + power sword
(chapter approved arrives)
combi-plasma + stormshield
combi-melta + stormshield
combi-plasma + power axe
boltgun + storm shield
I found I've mostly leaned towards dropping the frag cannons because they are so expensive, and because I don't find them particularly useful with the limited range (esp. if charged from +8"). If I get charged by something like 30 Tzaangors combined with getting smite'd, I lose too many casualties to really make vanguard + fall back + shoot frag to really matter. I'm having a lot of trouble dealing enough damage with my kill teams before they just get wiped out.
Mortal wounds is really a big problem, so I've ordered the DW Termie librarian so use as an HQ. Previously I've been using Watch Master + Artemis as HQs most of the time.
My next plan is to try to use two 10-size kill teams where every model has a storm bolter + chainsword. Jumping out of a Corvus with 10 dudes and shooting 40 attacks, followed by a charge for up to 32 attacks seems like a good idea to me. Alternatively I might do 6 boltgun+storm shield and 6 storm bolter+chainsword, for 2 squads in 2 corvuses.
The Corvus seems like a must-have, I tried to leave it out and used a land-raider crusader instead, but I found the land raider to be almost useless because it cannot fall back and shoot. I'm getting a second corvus now.
