Take out Sturms and let a volks be a Starter unit, because we all love volks.
I dont have any problems against Sturms, it's just like against PE in vcoh, you dont 1v1 them early game, you cap around them till you got a favourable Engagement.
Only time I get mad is when they are at 1/4 health and still 4 models because that can fuck up your whole early game, on the other side if he the Sturm loses a model in the first volley it's a easy early game for you, that's the rng we all love and hate.
You know the russian mark target is more expensive and worst than the CP mark target right? panther is 50% damage and mark target is 30%.
i think its good asymmetrical balanced. mark target doesnt have a range and it calls in a recon plane. its a tradeoff in my oppinion (not to mention SU doesnt have many muni sinks so the cost doenst affect them that much)
