Regarding your rounds exploding on leaves or tiny branches: look more carefully. This is a bug I reported long ago in the beta. If you hit the trunk or a thick branch the round will blow up and stop there. However, if you "hit" leaves or thin branches, the round will appear to explode with a graphic burst, but if you watch closely the round actually continues on towards your target and explodes there. I have killed many a tank with a round that appeared to be stopped by leaves.
