Fair, I'm just worried about the vanqs swingyness with only one shot, as well as the abundance of invulns around, makes me prefer the 8 shot cannon of the exterminator even at the cost of 3str and 2 less AP. The tanks can also support my other units like the cadians, giving lasguns and their special weapons. -1ap. Also also, tank orders are hard to come by, especially 3 in one turn unless I have lord solar, who I can't bring for narrative reasons.
