cc, WB2 had the B-25C(I think it was C), G, and J. I can understand them wanting to do something different so it wouldn't look like they copied it, but AH is most definitely its "own game" now and the B-5G/H is an overdue addition. The one we had in WB was extremely effective, we had times in the old HA when one or two of them escorted by a flight of 38Fs would wipe out a base in one or two passes. It even carried skip bombs, which were a godsend once you got the hang of them.
I don't know how you can compare the A-20 we have to something that holds either a total of 8x .50s and a 75mm cannon or 12x .50s. (plus the top turret, which could be locked forward on both models for an added pair of M2s)
Might not see all that much MA use once the novelty wears off, but it is (IMO) essential for a South Pacific scenario or CT setup.
