The wirble is just fine. It offers ground forces a modicum of protection, and that was badly needed. There's nothing worse than being in a good GV battle and some arsewipes show up in IL-2s and A-20s and just bomb everything. And this still happens anyway since the IL-2 got the twin 37mm guns and became an holy terror to tanks. Still, the wirble offers a sufficiently motivated and organized ground force a chance. It's good for the game as-is.
Unless you're an IL-2 or A-20 dweeb who is just mourning the loss of your the ability to pound attacking tank forces into the ground more or less at will, with the Ostwinds and M-16s unable to offer sufficient deterrence. Then, I suppose, the wirble is just awful.
But we're hijacking a thread on the HE-177.
Sure, bring it on. But on any list of bomber priorities, the HE-111 and some others really would have to be higher up than the HE-177.
