It doesn't matter which way you score the Stork, it performs the same. While in the Stork, you can see moving gv's 2700 yards away and if they are parked you can see them 1200 yards away. While in any other aircraft you can only see a moving gv at 1200 yards and a parked gv at 600 yards. The Stork's ability to mark targets and resupply via the air is quite handy, but if there are enemy fighters in the area it is as good as dead if it decides to loiter.
The Stork is not so much the game changer as is the "all other" aircraft's reduction in their ability to see gv icons. The other coding changes helped in making their day more difficult (no icon if hidden in buildings, under trees, etc). Considering that now that lumbering A20 needs to work a bit more to find its target (gv icon), and the keep sight of the position of where that icon was seeing as how the A20 is likely going to extend beyond the icon range before it turns back in for the bomb run, yeah it is over all more difficult for the masses to dive bomb gv's.
I'll be anxious to see the results after a few months.
