Don’t know about you guys, but I never drop in on turn one. Let the field spread out a bit, look for weaknesses as game progresses. Or reinforce a weak spot in my own line. Nothing as funny as when my death bubble of Hellblasters is almost finished off to only have a squad of Plasma Inceptors drop in to reinforce the bubble of plasma death.
Hell I love waiting till Turn 3, half the time my opponent forgets about them and there’s holes in his line.
use your reserves more tactically, don’t think of them as a sledge hammer force.
