It definitely feels like the most solidly designed faction. It has no OP units (save the Pwerfer) and very few mediocre/useless ones (222 could use a slight buff, PGrens a slight cost decrease and Brumbar more accuracy, but nothing major). Its playstyle is clearly defined, but doctrines allow you to go outside the box if you want to.
And they are still very strong. In the right hands, they are easily among the strongest faction in all play modes.
I'd rather bring things up or down to Ostheer levels personally. I think it's almost the best feeling faction at the moment.
I have to agree with you guys. While G43 grens w/ LMG42s would be cool, it definitely would break balance against soviets. Ostheer has a great, linear design with doctrines that can change things up which is good. I think that's better than having factions where your build is determined by your commander (like the okw commanders w/ mid game infantry, but that's been changed thanks to their tech changes). The unfortunate part for Ostheer is that their early game suffers, at least in 1v1s.
