Give it to all, or remove from USF and WFA.
Simple.
FRP is huge advtange on big maps.
I agree. I use this ability tactically when I play with USF, and it has a advantage when one or several infantry squads run into an ambush or became pinned. I know when I press a hotkey for the unit and the T-button, they retreat to the major, who is in a tactical position where I placed him.
Because I most often play 4vs4, I would wish to have one forward retreat point for both the Ostheer and Sovjets, for example the command bunker or the forward headquarters building. In 1vs1 this doesn't matter, but on large maps, this ability is an advantage, because you can make a tactical retreat, and then directly attack the enemy on an another position.
I know that in history in WW2, the troops had a point where to go, if the enemy break through the lines. Why not also in this game?
