BrINg back 6K Icon range and get rid of GV Dar. Make AH great again!!!
Reduce that 6K to 3K, thin the trees out a bit, eliminate the GV dar, and see how things develop. Told HT on the phone the other day that back when you could see the GV's on the ground, things were more fun. I think 6K was excessive, and 3K would be worth a look into...if not, make GV-to-air viz and air-to-GV viz equidistant.......you can't see the GV til 1.5K, the can't see/ID you til then either. Level the playing field.
On another note...getting that new graphics card helped a bit, but the bigger difference for me was moving up to a 32" monitor. The GV's are still hard for me to spot, but easier than with the smaller monitor I had.
