Multiple Sturms has been the meta since the last patch.
What?
3 Volks - MG ; 4 Volks (into JLI/Falls) ; 3 Volks - Kubel. I've seen like 1/15 double Sturms for every other type of opening. Never more than 2.
SU sniper is good against OH, when you can force retreats on squads. Against OKW a "wall" of Volks backed up by anything else is enough to force him to back up after the volley. When people say "rush them with Obers", it means just putting a Volk in the front and charge forward. It follows the same principle of playing with Osstruppen as OH (which is in fact better, cause you have a high damage long range unit which can shoot on the move).
-------------------------------------------
Since the best solutions are not possible (Damage tables or different Rof against dif squad sizes) i'll go with this:
OH sniper:
-Lower the cost to 340mp
-Lower RoF by 1s/2s
(Slightly altering the cooldown multi n/m/f)
(Still like 2s faster than SU sniper. Account also that you have a 10 mag vs 5mag)
-Add RA to account for the 82hp
SU sniper:
-Make flares vet 0 again
-Vet 1, while stationary and in cover, get increase LOS (60). Look, the spotter is not useless!
