I think it would be awesome if Crytek added a "Classic" game mode, that made armor and cloak draw from one larger energy pool. I like how movement no longer draws energy, I feel like it helps to give the gameplay a faster pace. However, I think that providing a game mode that makes armor and stealth draw from one energy pool again would provide a little more energy management for those who want it.
This is not to say I don't like the current system, but options are never a bad thing. I personally wouldn't care if the HUD remained the same, and both meters depleted simultaneously. Any thoughts?
