I think a lot of people weren't counting on the pumpkin chucker to be as effective as it turned out to be. In part because I think they were looking at the gun on the B-25G, which wasn't quite as good as the one on the H. It's about the best de-acking tool in the game (can knock out manned and auto field ack before they can return fire) and she's one of the best pure strafers and gunships in the game. Nothing else can single-handedly gun down a hangar the same way the B-25H can. All it took was a couple guys learning where to point that thing to prove she can be as good a tank-buster as anything with a cannon.
