To be honest, I still dislike the GV update, only because the distortion or opacity placed on some tank sights wears my eyes out. I think they should be clear. That said, tank fights now take place at the distances they should. Tank fights are also easier. What I mean by this is: With fixed zoom tanks sights, and with a moveable range graduation, it is much easier to be consistent with hit after hit. With the old system, the urge was to change the amount of zoom, which resulted in a shift of your aiming perspective relative to the range of the vehicle.
I still believe that there should be places on all maps where it is exceedingly difficult to bomb GV fights. The Grinder map (more of these) is a great example. The perimeter is lined with V-Bases, all lined by high canyon walls. They have little strategic value, and are in depth, so if some one captures on, there is probably still another out there.
If I were to make any recommended change to promote "fair play" I would say changed the graphics slider to have a GV and airplane setting. Currently you can reduce your vis range to 1.5k. Meaning, you can turn off all trees, etc... and then you would start seeing things. This used to be OK, because tanks were shooting 3k with the mega zoom sights so if you wanted to have a prayer of defending yourself you had to be able to see that far. Now, I feel most kills I have gotten have been in the 800-1.2k range. (good armor model). I would recommend that the slider brackets be 500m/3k/5k etc.... to prevent guys from lowering their settings and getting an edge. This I think is why some guys feel there are being "shot through trees" etc....
Still a thumbs up from a very vocal "I hate the GV update guy". Please clear the sights up if you want to keep a guy like me online for an extra hour. It just hurts to squint at a "foggy" tank sight for very long.
