Delta I think alot of it has to do with lack of targets. You can bomb a town, but it gets boring unless a capture is in progress. You can bomb a field, but many times its unnecessary if town isnt dead. Plus hangers re-up way too quick to make it worth it. You can bomb base strats..but fighters can strafe them just as easy. Acks can be hit, but it takes so many passes it gets away from the feel of doing a bomb run. That leaves CVs which die too easily, and factories which amounts to no affect to anything.
I bomb primarily to shoot down fighters when Im tired of flying fighters. The bombs are an extra.
Hopefully the CT will provide a better bomber setup.
