I made this as its own post, but it’s pending forever:
I think this game would really need some kind of game mode that incorporates Air (planes & helis), Land and Sea, and this probably always had been the original goal of the game. But not in the way of GRB and its stupid CAS. So here is an idea of how to do it:
What if we could have air SIM EC sized maps, or even larger. In this, we have ARB EC going on (3rd person, mouse and keyboard, ARB flight mechanics, no enemy markers but yes friendly markers). Combat planes, bombers (and helicopters?) can spawn here with infinite respawns like current SIM EC. Games can last multiple hours.
But now, in some sectors of the map, a GRB battle is going on. Maybe protected by SAM sites in the rear (like we had in the event) and ofcourse by spawned SPAA in the GRB battle or even outside it at the area of the heli-pads.
Now, if a GRB battle is lost or won, there will spawn new GRB battles, in new sectors, depending on the outcome of the previous battles, so basically in the main ARB EC, the game and frontline is progressing.
So basically the ARB EC can provide CAS for all of the GRB battles going on. And there are multiple (independent) GRB battles going on the air map. Maybe there needs to be some communication / spotting for the GRB players to ask from CAS from the planes. Maybe recon planes could have a special function in spotting. But otherwise I think spotting of ground vehicles should be pretty difficult (eg. no markers etc.).
Maybe even a naval battle could be going on in one of the sectors.
Of course this needs complicated map design because all of the map sectors needs to support GRB (with proper spawn points and caps and every sector needs to have interesting design for GRB etc). And maybe it’s a bit complicated from a server point of view, as it needs to be a single server that supports maybe 100’s of players (multiple GRB at the same time as well as the ARB EC battle)
