The Wehr are suffering a lot more early game tha the OKW right now due to the shitty survivability of their mainline infantry if not again for their othet 2 infantry units, those being the pioneers and PGs. And late game due to their underperforming armor compared to all other Armies.
So the most logical step is to buff them, if you don't agree with that then suggest something else but don't bash our opinions just because you think yours is superior or something, if half the forum is suggesting a certain buff then it's up for debate and testing, not being bashed by some new comer modder that thinks he has some people here's experience and knowledge of how the game works.
there are other ways of buffing the wehr without giving them a fifth man, which would destroy their identity. Better squad spacing and better received accuracy are two examples.
and the problem is the power creep on the USF and mortars in generals.
and I've already made my suggestions here:

and let's not get into a pissing contest about who's been playing the game longer.
and regarding tiger:
It's a victim of the introduction of the King Tiger. The King tiger is significantly better armed and armored while the difference in speed isn't that great. The allied TD are tuned to counter King tiger but it leave the tiger in the dust. Tiger is bit a faster but not fast enough to make a difference.
Either the Tiger get buffed into a King Tiger clone or the Tiger get a mobility buff to differentiate it from the King Tiger.
