Ever think to tell the fighter pilots that there are 6 tank hunters at your location? I bet if you had there would be a dozen Doras there in short order to feast on them.
The problem is not the GV dar, it's the GVer's desire to be isolated from the rest of the game.
1) With the numbers nowadays it's hard to recruit people on short notice, even when the payoff would be low and heavy GV hunters. Especially when transit time to target in such a situation would probably be longer than the survival time of the GV they were hunting in the first place. If anyone ever took you up on that bet, you'd lose.
2) What on earth is your issue with GVers? This isn't a rhetorical question: I'd really appreciate an answer, because I read what you said but I just don't get it. Even if GVers "desire to be islolated from the rest of the game" (which isn't true, but we'll run with that for now), so
what? It's their $15, and if that's what they like why is it an issue for you? It wouldn't impact your game play experience in the slightest.
