Derp yes it was the sniper. Scratch that then. Having had a play with the numbers of a Marksman Draal vs a Sukeul Hmg against more usual targets I'm pleasantly surprised. The Draal is about 1% worse for killing power against b2 targets but around %5 less likely to take a wound from them. None of this is catering for mates either, where the Draal survivability presumably goes up due to the reduced crit chance.
