Let me start by saying I really like AH3. Even with all the graphics disabled except details and ground clutter it is much better than AH2. Just wish I had a better video card.
What I don't understand is that a Panzer will roll over about 20-25% of the small trees but is stopped dead by the other 75%. I'm referring to those that appear to have trunks a less than a foot in diameter.
I understand the really big trees stopping a tank. That I would expect.
There is no advantage in game play if we can't tell which trees we can drive over/through. If many small trees will stop a tank I think most GV'rs will avoid hitting any trees just as in AH 2. So the fact that we can drive through/over a few of seem to me to be of no value.
