I think I have to disagree on the StuGIII (without having played the updated map, arguable).
For me that's too much direct-fire HE, it doesn't have MGs, fair enough, but still dangerous to infantry hiding and defending objectives. You would need to give the russians one or two PTRDs to even it out, which in turn is a problem for the halftracks and means they would not longer be used as real transport since they blow up frequently by a good hit.
Also, I'd hate to see a long-barreled StuG on a Fall '41 map. They only came into service in '42, for this map we would need a short-barrel "E" type.
IMHO, for this map people should learn how to use the halftrack as transport and fire support. But if they keep driving up right to the farm, jumping out of the vehicle and getting shot in the back, no wonder they will think of russian "dominance".
As for the third objectice...I actually would like to see that. The stretch of trench right now gets little use, most people are rather "gamey" sneaking on the map edges which is a tactic that works for this game, but not very realistic. Making the trench an objective will force the germans to attack over open fields and thus employ their fire support correctly, use smoke etc. Makes the map more linear, but also requires better tactics.
BTW, I like how Beta3 (the preview you sent me) actually has the road blocks in front of the last objective. Prevents people from suicide-driving the HT up to the tower, but still allows it to be used as mobile armored MG station.
