Wait a couple years and most of these things will be fixed. Don't like it, then go to a game that has more adequate resources and personnel to develop their games, like Blizzard. Relic is too small (and, as much as I don't want to add it, incompetent) to be able to put out such complicated games without these errors (unless they applied lessons from coh1, but I digress).
It's funny because every complaint for this map can be said about every other map, minus one, forgot it's name. Maybe langreskaya too, haven't been allowed to play that one yet.
It's important to use mobility to make it so that recrewing isn't a valid reaction, or is a costly action at least.
After decrewing the unit for the first time, move your units to the flank of it's current position. Therefore if the enemy wishes to recrew it, he has to lose what offensive power he has on your current location to recrew the weapon, pick it up, and reface it. This amount of time allows you to focus-fire the weapon while taking minimum fire in return.
