Me too more or less, but at least three Fausts for one Schreck? Definitely something I'd take. The new SP Schreck should also make SP replacement a lot more feasible to deal with actually.
How? Should you repair your panther or be handheld AT on the line? Put down barewire, mines or emplacements or be handheld AT on the line? Detect mines or be handheld AT on the line? SP have to many jobs already, requiring them to fill the AT role as well is yet another poor design choice. To fill all of their roles you will need 2-3 and that comes to 27 popcap and the bleed from having them on the front line is going to be difficult to deal with.
Futhermore, the STGs package is a joke and not really an upgrade.
