Zoney, you know I fly aircraft, and am a decent pilot. Yet I GV a lot as well. I and people like me are the hole in your thinking. Nobody on the ground needs to learn to fly; in fact quite the opposite is true. Most gv bombing seems to be brought about by a tank driver being killed and getting pissed.
Basically if you bomb GV's, you need to learn how to tank, or your VH is down.
@ Karnak, I think cutting icon range for friendly GV's in half is pretty damn generous, since your wish would completely kill teamwork between the two groups. But hey, if you want to further the "f**k you, other players" attitude that has been popping up in the MA, on your head be out.
And if you want to furball over a GV spawn, you're gonna have a bad time. Deal with it, it's part of the game, and won't change significantly if you change friendly icons. But if you're twisting things, and are still talking about the runner problem, suck it up, it happens less than bombing.
Come to that, I don't think I've ever had a runner drag me to a Wirbelwind.
