Good grief! Broaden your horizons guys. Where there is an offense, there is a defense to counter it. Tankers don't like being bombed? Ask for some friendly fighters or AA vehicles to come to the area. Don't like being shot out of the sky by non-aircraft enemies? Fly smart in a group to use one guy as a distraction while another gets the AA gun from behind. Don't like hordes? Then up something at the first sign of one (most are NOE), so get get some alt/energy and fly smart until you get backup.
All I'm seeing is a lot of "I just got killed, so there's either something wrong with the game or the enemy is not playing fair"
Back on topic with the 88 flak. Ive gotten 2 kills as a result of direct hits less than 1.5k away. Its tough to handle because you have to give the shell anywhere between 1-30 seconds to get to the target distance. I wouldn't waste my time on fighters, another fighter or LAAG would be better to stop those. Since bombers are coming in straight and level, that reduces the variables by a lot. The toughest part about it is trying to quickly change the fuse lengths because they are carried out to a hundredth of a k-yard. You might have to set the fuse as much as 3k in front of the plane to get even close. Ive only been back one day, but my initial impression is that operating a single flak is not enough to pose a serious threat to high buffs, but could possibly distract them enough to make a mistake. I don't know, haven't been on the receiving end of one yet.
