I don't know that I've been bothered too much by them near airfields. As I said, one reservation I did have about making this suggestion is I want them available for airfield defense when an airfield is being overwhelmed.
My main problem is when a bunch of them attack a town. I'll admit, as much as I enjoy the WW myself, I also LOVE gv busting and my latest thing is going after gvs in a b25. B25s are too easy of a target for a WW, imo, especially when there's three or four WWs and they keep getting resupplied.
Another thing I've found, with b25s is, by the time the icon of the WW shows up I'm already in their kill range and the 25 is so sluggish it's hard to get out of the line of fire in time. Switching to a quicker plane can help with that, but I know that no plane is safe around me when I'm in a WW.
Of course, alongside WWs, the biggest annoyance for me when I'm tank busting in a b25 is enemy planes showing up.
