Yeah the Wirblewind will make it easier to protect fellow gv's from air attacks, like if you got a gv mission to attack a town, you take a few of those along and you'll have really good air defense, much better then using the flaks. Flaks were hard to get kills with unless you had alot of time in them and had mastered it, but with the Wirblewind just about anyone can use it and get air kills.
