One rifle nade is usually enough to wipe the entire squad or force it to retreat. Unless it's behind green cover. With OKW, just come from at least 2 different directions or sit behind green cover with at least 2 squads.
If implemented as is, I think we would be in a better place in a lot of ways. However there are some pretty major changes, and as with the official patches, I can guarantee there are some unforeseen consequences.
I agree, though I think making the situation even worse would really require some effort
