That's literally how shocks are supposed to be used against ALL infantries in 1 on 1 situations.
If you aren't going to hit shocks with nade, you're going to lose the engagement.
If you want to beat shocks with small arms, you better have plenty of them.
This. Falls are not supposed to beat Shocks 1 on 1 (nor any squad for that matter), but they can do significant damage against them if you've got them backed up, pop Valiant Assault or just retreat once the Shocks come close.
What I would do with the Falls is fix the late timing of their second FG42 package and lower their dps a bit for Stormtrooper RA (0,83-0,59 -> 0,75-0,53). With the Command Panther tech lock, I feel Luftwaffe will become a top 3 OKW commander anyway, with 4 strong and verstatile abilities. Hell, even tank traps, trenches and Flak can be useful at times.
