But it doesn't make it a good ability that you can integrate in a strategy.
I agree with Hector, the idea is to spam as many vehicles as fast as possible to completley overwhelm your opponent, normally this would be a crazy all in strategy where all your opponent has to do is survive to an Ostwind and counter all your light vehicles, but this ability lets you pull them off the field so you can bring out a sherman etc.
Also allows you to go a bit heavier on shermans, when normally you might be worring about a heavy tank eventually, punish him harder before it arrives, then W&R into Jackson when you need it.
Also the Jeep can win the game in first few mins with a couple of wipes quite easily if opponent is not carful, so something with such early game power does not need to scale well.
If you think of the advatage you should gain by having *more than ussual* light-medium vehicles on the field, that should be enough of a map advantage that it outweighs the ressources you are losing when you do W&R.
Also the arty off map is not bad at all for punishing OKW trucks, esspecially at 8CP. Its almost a perfect OKW killer doc if you ask me
Personal prefference of course.
