They should just reduce the price on it. Its a HUGE investment and rly depends on the building. Could use a balance pass to be 30-40 fuel rather than 60 but being able to repair ambient buildings I feel is silly.
No, I mean just be able to repair the FHQ, not all ambient buildings. You can easily hard counter it by using a walking stuka or panzerwerfer, which almost always destroy buildings with 1 barrage.
