You guys are fixated a lot of the aircraft vs Gv aspect.
Now that the quadrant has been reduced to 200yards, it's much less of an issue.
What remains is the impact on pure GV combat. And I'm still very pessimistic in it's impact in terms of 'quality' (yes, a very ambiguous term).
Even when on the move, you can detect and easily pinpoint an enemy tank totally out of sight up to 6k away. And that's not only those "hiders" you all seem to be fixated upon. Let's give an example:
A few weeks ago I was fighting in my M18. Was two of us defending a town vs a sustained, Gv only attack of 4-5 enemies. One of us stayed back at the town. Considering their numerical superiority, I decided to venture out in a M18. Highly mobile but extremely fragile. The only way to employ this vehicle is shoot& scoot. And so I did, putting up ambush after ambush, quickly relocating and greatly changing my lines of approach, sometimes hitting them from the left, then from the right again.
With the GV quadrant, that would hardly have been possible. They could have easily seen me flanking, no matter how far out of sight I'd been driving. They could have determined my direction down to a few degrees, thanks to the sharp boundary between the quadrants. They would have easily noted how I switched from their right to their left side.
Yes, I could adapt to that - by not choosing a M18 anymore, but a much better armored vehicle and sit back at the town to slug it out again. Or even better get back to planes to simply bomb them.
You don't have to think much anymore, you don't have to 'look' for the enemy that much anymore, and combat tactics based on outwitting and maneuvering are much less feasible.
The new terrains introduced quite a problem in vehicles finding each other for combat and have caused a massive reduction in vehicle diversity. The quadrant, implemented as is, would be a bad way to fix that problem (if this was the intention at all).
And I'm not even talking about the 'gamey' aspect on looking your map for a 'radar' picture in a WW2 tank instead of looking out of your hatch...
