Sorry for off-topic connections here, but hear me out...
I've wishepered here that Battlefield 2 and 2142 styled field commander should make a return. With destructible-repairable assets on home HQs, there'd be dynamic depth of defending and attacking (destroying and maintenancing) key strategic installations. Same with dynamic bridges under on-going warfare around the map. Control the flow, to blow them out!
Battle dynamics, chain of command and clear communication between players (commo-tactical rose, strategic map views & color-coded smoke grenades) would drive both feeling of reason and urgency to combat. Focus is currently on going on personal kill streaks and squad wipes, rather than thinking and communicating clearly your actions with your buddies.
You're disposable part of machine in this game. Your actions as a single soldier either has 100% or 0% value. There's no grey area, I feel, where killing and/or damaging enemies and pushing forward or creating succesful defence would matter. Everything is immediately replacable.
