If it too much hassle one can simply replace crew disembark with the version already existing abilities of OKW on Ostheer of self-repair...
Crew repair isn't going anywhere nor should it.
USF can jump out and repair crit because its armor is (relative to OKW, OST, UKF, and to a lesser extent, Soviet) pure paper. Its most survivable tank -- the Pershing -- has less armor and the same health as a Panther. And that one can't be decrewed.
Do we really want or need everything from every faction to be the same? To have the exact same strengths and weaknesses? Why even have Americans and Soviets and Germans and Brits when we can just have mirror matches?
It's frustrating to see threads like this and comments like:
Pak and Shreck are irrelevant when comparing the Tanks them selves.
No, they're not. At all. USF armor and AT options are outclassed in all respects by Axis counterparts. Far easier to kill, often w/ less micro required (e.g., drive Panther straight at any US armor and win, drive any US armor straight at Panther and lose).
Taking AT, the health, armor, mobility, and costs of the tanks into the equation, it stands to reason that USF has an ability that allows its armor to survive and get back into the action fairly quickly.
Sheesh you think USF late game is poor now and you want to remove crew repair, lol. Better buff USF early game even more because the faction will have no chance past the 15-20 minute mark w/o survivability buffs to all of its armor, up to and including the Pershing.
