+1. They are far too weak (on the resilience side) to be reliable. Most of WM troubles come with their inability to hold areas of the map without having MG42 setup there.
That is a problem why?
The faction is designed to rely on MG42 from get go. Grenspam strats are dead, because they were never intended to be a thing.
Then the 30mp / model bleed starts, and the slow death is on the way. I do think that Wehr players would gladly pay 280 / 30 for their grenadiers if they were 5 men squads, and the end result would help the faction in 1v1s.
Grens don't bleed more or less then any other mainline inf because of rec acc and their own firepower, unless you insist to fight in close range with rifles all the time.
Ost struggled vs early light vehicles, which was fixed by band aid 222 buff to boarderline op cost effectiveness in relation to any other light in game.
The whole idea of 4 men squads at first was that their were "elite infantry" when compared to Soviets' conscripts, who cost the same, but have 6 men to compensate their poor model to model comparison. With WFA and now Brits, Grenadiers are no longer elite, even if they stand their ground verse tommies (before double lmg and 5th man, obviously).
Wrong, the 4 men squads have nothing to do with them being elite or not, its to support army design of combined arms, you can NOT rely on grens alone, you need supporting units, either support weapons or command bunker/251 for map presence.
Grens never were supposed to be superior to any other infantry squad, so your elite argument desn't apply, they are supposed to be equal to cons and surpass them with weapon upgrades. Vs brits and UKF you have to use support units, just like UKF needs to do to support tommies.
