the only problem with Static AA on most maps, is you must lure the enemy fighter or bomber into your airspace or near your hq where most of your AA is and i know this is a good tactic n all...but who the hell would follow an enemy plane into his Airspace where their flak can get you and possibly other fighters!?.
I really do think the allies should have some mobile AA to at least give them a chance, i mean armoured columns get ripped to shreds by dive bombing stukas by not having any air cover its a tankers worst nightmare hearing that siren first minute your alive, last minute you are dead!, allies must have new equipment in FH2 as the germans already have powerful tanks "which dont bother me by the way!" because they can still be destroyed....im just thinking most people are leaning more towards the germans than the allies :/
