Hitech put the enemy distance markers on the bottom when viewing them instead of the top like the friendlies, because on GVs that big ol' neon maker on top of them made it pretty easy to find them. Then they changed vis range on the GVs because at many angles you could spot them pretty easily and the GV guys were getting slaughtered.
Then we got our little spotter plane with the better range viewing. Not long after that we got speed trees and the ability to disappear under a tree even to that.
Then came the GV "dar" and the tankers that had built a bit of a community with in the AH community began to leave. Why? Well its kinda like have a big ol' neon sign over your tank saying here I am!
I'd like to see two changes to bring back the balance that has tip way too far off from the GVs.
1. remove at least 40% of the trees! Especially around fields, bases, towns and strats. Keep the heavy forest out away from the built up areas, maybe 5 miles out. When building up an area the first thing to go is the trees, why do we still have so many?
2. Make GV dar only come on for a gv a mile or so outside fields, bases, towns and strats. This will more accurately the "spotters" spotting the vehicles as there would more likely be more people closer to the bases/fields and such to spot them. Also more and more fight should and most likely would be around the bases and such so it would make it easier for the new guys to "find a fight" which the new GV dar was for in the first place.
This would give the GVs some ability to "hide" while traveling to..... where ever. It would still give players a chance to find a fight, yet not make it so GVers can completely avoid a fight. I think this would be a decent compromise between what we have and what a better balance would be.
