Meta units will be adjusted if necessary, but how would you buff LMG Grens:
early / mid / late game?
raw firepower / bleed / durability / scalability / utility?
The G43 upgrade won't be touched for now.
The problem with Ostheer is that they are a defensive oriented faction and are terrible at attacking.
The changes making the pace of the game faster, the high lethality of allied infatry, the weaker mortars, the reduced shock value of PzIV and allied tech more accessible have amplified the problem.
That is why the have to use specific aggressive commanders like assault grenadiers, 5 men grenadiers/fast 250 or fast capping commander like ostruppen, in order to secure sector else they are simply strangled.
