On trees.
Palm trees are my least favorite for sure. They can be so tight they can trap you like a dead end cannon in an old western. They are fine trees but not packed so tight you cannot see a clear, but still jagged, open path. I think palm trees catch the most negative chat on Range radio.
How many trees is a good question. Too few suck. Too many suck. I would suggest giving a GV'er the option to go around a large group of trees where practical at the GV'ers expense of lost time. I would also suggest long GV runs to a combat point have more open paths through trees than short travel to combat points.
As others have posted, the map makers, and skin makers have really helped to keep this game going. No complaints here, just feedback.
