Mate, I clearly stated that 1 schrek costs similar to 2 PIATs. Maybe you should look a little deeper next time at the point being made before you mouth off. Double PIAT squads is a VERY common occurrence. On the other hand, single schreks were considered OP on volks.
Just watch this video I kindly made for you just now, so please use the video to rant about the TRUE "OP" AT squad here, especially if you are going to use upgrade pricing as an argument:
UKF: Mines, Piats, AT Gun
OST: Mines, Shrecks, fausts, At Gun
OKW: Mines, Shrecks, fausts, (invisible, retreatable, tier 0, garrison-able)At Gun
How DARE UKF have a slightly cheaper but worse handheld AT! How dare they!
