Not sure if you heard my points last night on the Aussie / NZ server.
There are a few patches of indestructible grass in F (Eastern Forest) where bullets get blocked as well as explosives.
Mortars randomly dropping throughout the map would be alright, as long as it wasn't in predetermined spots and it was truly random where they landed, then I'd be alright with being killed by that random factor.
Also maybe the mortars could stop dropping once that bunker area where all the mortar positions are is captured by Axis?
The bunkers currently cannot see down the hill, but are usually very good to use when taking out people to the sides of the bunkers (the destructible ones in E I think), or were you thinking of replacing them with sandbag fortifications?
The half dug trenches you can get stuck on if you prone in some spots.
It is also difficult for Germans to see Russians when attacking up hill due to the bright sky box which makes it hard to see silhouettes. But once you've captured E and F and you move onto the heavy trench area before the AA guns, the lighting becomes very dark and saturated in the trenches (which I like - shows how grim the battle has become once you've reached the top of the hill and the ground becomes less steep).
Apart from those things which you probably already know about, I am loving this map. Love it to death. The hardest part about this map is not getting bogged down for too long on one point. The tickets seem just about right, but you have to be very wary of the time limit so you will find that you have five minutes to clear the AA guns and push onto the final point.
Also if you have tree's that get blown up, perhaps somehow replacing them with fallen ones would be good (if that isn't too difficult). There is very little cover for Axis assaulting the E and F without the tree's save the dead ground of some of the rolling hills. Also Russians with log fortifications would be neat to see. With ample tree's, I don't see it as unlikely that the Russians would cut down a few tree's and lay them down along the edge, might serve as an alternative to sand bags and barbed wire fences.
