In my opinion, future of the RTS genre=FPS+RPG+RTS+TBS

As a commander, you can manage all units, but you can't see the combat directly (FPS+RPG+TBS+RTS). All information won't come to you immediately and come to you indirectly, it takes time (TBS).

As a squad leader, you can manage your team directly, follow the commander's order, but you can't see the whole battle (FPS+RPG+RTS).

As a squad member, you must fight the enemy directly (FPS+RPG).

If you died, you could choose between those characters to play in single player mode. In multiplayer mode, you could choose between characters who weren't chosen to play. 

Thousands of soldier, hundreds of officer play at the same time. They can not be re-spawn. Before you choose a character, you must look at his status if you don't want to play the injured. You can see the list of your soldiers and officers; you know who died, you know where the characters' unit is, that's all. You won't know where the character is, how is his status if you couldn't communicate with him.  

I always try to bring reality to game.
