It's got less reach than the ostie and is just as vulnerable to bombs or rockets, or high ROF guns, if only people follow some minimal tactics. e.g. Two planes in from opposite sides, with the one that gets shot at pulling out, while the other just disables the vulnerable open turret.
It's not 10 times better than the Ostwind. If you're going to say that, show some supporting quantitative evidence that it actualy is "10 times better".
The WW will force players to follow better tactics, and that's good.
