I am not keen on having very high terrain near the central ring of SPs that could be used for long range spawn camping. I can't stop short range camping, but at least the victim has some sort of chance of firing back and the camper can be outflanked from neighbouring SPs.
Greebo, in my experience "long range spawn camping" isn't really possible. This is because it is difficult to hit something in motion at over 2-3K. Instead, what you do at long range is wait until someone has moved forward from the spawn point to their combat position, is stopped (hopefully with engine off), and paying attention to closer opponents, and then to in a sense "shoot them in the back". Doing this usually takes several shots as you range in, which is why you want them distracted and/or with engine off. Also, usually the only way to get a line of sight at such long ranges is to be at a higher elevation. Of course, LOS works both ways ...
The terrain vertices in AH3 are closer together and can be set to a vertical resolution of 1 foot rather than about 63 feet for this terrain in AH2. So I can now make small rises of 20-30 feet that will hide a tank. This should make it easier for players to outflank each other using cover. I'll have a look at extending the coastlines around TT a little bit, making them hilly rather than just a straight slope down to the lake shore, but I don't want to go too far doing this as a larger area just dilutes the action.
Admittedly I haven't (can't) tried out your new crater terrain due to my aforementioned hardware issues. However, I don't think you need to worry about extensive hilly/covered terrain surrounding the main fighting area “diluting the action”. My general observation is that most GVers drive straight towards the nearest action (on all the maps), and so will still gravitate towards the center of your crater. Some may try for flanking positions. But, if these flankers are perceived as being effective, others will then move to block/ambush these flanking moves, and so play balance is preserved. IMHO, such GV maneuver options are much more interesting than sitting on the firing line all the time. BTW, you don't want to limit yourself to discrete small hills, but also a mixture of areas with long fields of fire and some where longer folds in the terrain provide covered approaches.
I know you like to take potshots from 5k with a Panther from up high where you can back off of the edge easily. Since the terrain no longer has the sharp edged polygon surfaces your tactic is not going to work anymore, anyway. (deleted)
Chalenge, FYI a Panther is the last thing you want on the current CraterMA TT cliffs, as it lacks sufficient gun depression. The best GV for that is a Panzer or M18, actually.
WRT taking up hull down positions and backing off when they have your range, this is a standard tactic, and does not require “sharp edged polygon surfaces”. In fact, sharp-edged terrain modeling hurts those GV's with gun depression issues (usually those with longer barrels such as Panther, Tigers, T34/85, Firefly, etc.).
And yes, once they notice you up there, they do “shoot back”.
