The area a GV will be operating around a field due to the average distance spawns are placed from feilds is about a 6 mile diameter. Hitech could always change the block dar to a 6mile diameter color inside of the 18 mile aircraft dar ring. Maybe too much visually since the relatively small blocks are visually easier to notice. Have it stay up like the blocks but then it does not semi pinpoint a GV, just says one or more are there until they are destroyed or the base is captured.
The dar blocks at least on the rook side where I play don't seem to move people to intercept M3 which I've witnessed base assaults fall apart with everyone yelling about how were the town guns not staying down and they could see a dar block at the spawn the whole time. I watch more players wait until they see a main gun tracer before they start looking for tanks while a dar block has been sitting there for some time. Trees foil the dar blocks unless the GVer has decided to move across the terrain. Once the dar block is sitting on the field, I watch everyone not be able to find the enemy tank no differently than all the years previously to dar blocks. And everyone yells the same things at each other and runs around in circles PO'd at each other like they did before the dar blocks.
It seems for some players the dar blocks are not as helpful as other players in locating GV's. And shutting down under a 5 tree canopy foils the GVDAR well enough using a film is now a gamey standard GV locating tactic. And it works as far as I can tell 100% of the time. There is something not right about that in a sense that many GVers have adapted to the new trees to solve their problems with being bombed in very skilled manners. While running a flim takes "zero" skill to get a kill on them.
I don't like GV's but, I spend an inordinate amount of time at the GV level of my terrains building terrain for GV "customers". They are as important to the future of this game as airplane players. So it's easy to appreciate the imbalanced disconnect of a GVer working very hard to become skilled at hiding his tank in the terrain while anyone with no skill other than knowing how to turn on the film recorder can minutes later destroy that GVer. That is wrong on so many levels since this is a game and not a real life war where our lives are at stake.
