First, sorry my english, I am from Spain. I dont usually argue on the forums cause my english... but the topic is interesting.
I think you are watching the game from a wrong point of view, this game is not a sandbox nor PlanetScape 2. In fact, actually, this game is unique and maybe it is not a game for you.
Like other people have said, the map is too big and we need to focus the action in some places, in the old days there was not Early Warning System (EWS) not AO's or DO's... so it was dificult for new players to find the action.
The essence of the game is that you are a small piece of the war machine, under the command of your High Command Officers, that orders you during the map. You can be a small piece or a CinC of a whole Army, its up to you. Think that you are a soldier and a soldier just obey orders, a soldier dont take decisions, the HC set an AO and you must obey. If you want to plan attacks, move flags etc. join to the HC of your side. Sure the are pleased to have a new member.
You have to capture a town, and you or your Squaddies are totally free to conduct the operation with the rest of your side and your AO OIC. Maybe you can set a Zone of Control in that Southern Hill or maybe you plan a ninja cap. You can set Fms's, reaload tanks, guns, grab a sniper or LMG and cover our tanks advancing etc. It takes time to view and use all the game potential but when you get to it, it is a very fullfilling experience, at leats for me. Like I said, maybe this is not a game for you.
For me, this game brings much more satisfaction than ARMA 3 and SQUAD and Foxhole... (games that I usually play). I have been playing since 2009 I even today feel the adrenaline trough my veins when I try to sap a sherman or try to kill Nily or Gretnine or any other allied player. Or when i hear footsteps while defending a CP, your heart starts to beat as you try to concentrate on knowing where he enter the CP.
