I think Hitech pulled in the area around trees that catch tanks some time back so they can get trough thickets. And I've noticed a lot of bushes and even small trees can now be driven through. If you pull into the middle of those drive through types and shut down, it's almost impossible to see your GV from the air.
Cybro lands an SBD into bamboo groves, bushes and small trees, shuts down and players now just run a film to find him.
I was trying to deliver supply's in an M3 and pulled into a bamboo grove and shut down. The red guys just flew over me and didn't see me. One of my squad mates told me he was in an M4 and pulled into the only bush in a field, shut down and the red guys could not find him. He got a bunch of main gun kills on planes before they figured out where he was. He suspected they ran a film.
I watched an M8 do this while circling in a storch. It was pulled into the only green bush for 100yds in the open. I allowed myself to be killed many times to see where the tracers came from and try and determine if I was looking at a bug to report to Hitech. I asked a tank to drive up to the bush and see what was in it. The player was a few yards away and said nothing was there. I asked him to lob a round into the bush and he got an explosion from the M8 blowing up. It surprised the heck out of him becasue he only saw a tiny green bush in front of him.
The GVDAR block is an equivalent exchange I suspect for that semi invisibility. Still, players are opting for the film more often as their first line of finding GV's after a very short time investment trying to find it from the air. This whole thing is evolving our game play on both sides into blatant gaminess more so than a fun combat game. If you don't find the gamey GVer and leave out of frustration for the fun you are really paying for. You have just given your field over to one weenie because of how vulnerable our feilds really are to a single unopposed tank. Funny how feilds auto defend themselves better against planes but, not tanks. If you opt to stay, being frustrated, you film, locate the GV then egg him. Then the GVer ups again and some people allow one player to eat their evening like this making them dislike the game. Others give the greifer the field becasue they are paying to have fun and not be some griefer's girl friend all night long. The greifer wins both ways and makes players dislike the game while not caring if the doors end up closing due to no customers. The competitors have some great Quake Tourney style mini terrains and good graphics so the greifers just move on to the next game.
Our game is slowly devolving into an 8th grader mentality greifer game this way and not a combat game. But, by today's cultural norms, the whole paradigm of combat versus greifing dressed up as something noble is being tilted towards greifing and getting away with less than noble intentions. And the competitions tiny arenas glorify and promote it. Since so many I've watched in my research of their videos just drive around and greif each other paying lip service to any idea of combat. Looks like just Quake Tourney in tanks. That is why I keep describing their games as super mario brothers keystone cops with shot guns, or greifer wars.
