Sasquatch, protected zones! Seriously! If for no other reason than at least a quasi-historical treatment of the battle. If the Germans in RL had done what players do, it probably would have been the Germans having their post victory party in the Grain Elevator.
Squad leaders should be taking their teams to defend different zones. The entire squad system is as yet completely under-utilized. If Russians placed 1 squad in elevator, 2 in in B and the rest roaming with a LOT of VOIP to communicate and players to actually follow through and go back to their objective it is held.
I don't believe needing full squads off the point to stop a flank maneuver is fair to the Russian team. They have to divide their forces to successfully defend a single point? Hell, the Germans don't even have to split their forces to win the point, they can literally do it through brute force on the ground floor. The reasons the Russians never defend C worth a damn is they get pincered, and when they have to hold out for 10 minutes at C to win because they didn't bother defending the rest of the map....they can't keep up the momentum.
Add on to the fact that the Germans basically set the 2nd Floor up to be capped THE INSTANT Ground Floor falls, and it makes a Russian player ask exactly what the hell is the point of defending an elevator when the enemy is above you before they've even captured the floor you're on!
Compare this to, oh, just about any other Russian Attack map. The Germans have the easiest way to avoid the Russian's primary strength in Grain Elevator by simply NOT attacking the objectives in order. Can you do that on Red Oktober, Spartanovka, Commissar's or any of the other attack/defense maps? No.
Protected zones on the upper floors of the GE makes sense for several reasons, not the least of which would force the Germans to actually assault in a logical fashion...instead of basically running to the back of the map FIRST to start attacking.
