I have thought about it for last 10 mins and that actually doesn't sound bad.
Grens are superior long range fighters anyway, cons still wouldn't be able to dodge automatically vehicles and be easily run over unless they hit retreat.
The only issue is crawling up to the MG42 with molo and creating new Niagara falls of german tears.
This ability will be hard to rebalance, there is completely zero pros to get conscripts stationary, but many cons.
Ok, I see that a thick layer of bias is blocking your common sense a bit, so let me explain:
cons cost 240
grens cost 240
It is mathematically IMPOSSIBLE* but still needs to be reflected.
How to do it then?
By model basis. Single grenadier is stronger then single conscript model, to the point where you need MORE conscripts models to stand up to LESS grenadier models.
AKA con squads have more men then gren squads.
AKA you need more cons to have the same(but still lesser in this patch) impact on the battlefield.
I really hope you are not a man of religion thou, because they don't seem to believe facts that go against their beliefs, no matter of how well presented, logical and evidenced they are to them.
It used to be op a long time. They nerfed it to be useless except as a tool to own MG42s by avoiding suppression. Now that everyone is busy spamming out 5+ grens with no mg42s it's just useless except for baiting your opponent into riflenading squads you'd retreat anyway.
Even with normal BOs with MG42 it would still be useless because of weapon profile which makes sure conscripts won't hit anything smaller then a whale unless they stick a rifle in its butt.
