Stealth and Better A.I

[shukkoku]

If you have played metal gear solid, you would know how important staying undercover is. I was thinking that they could adapt a bit of stealth into BF3, perhaps you sneak around the battlefield and avoid detection until you engage the battle. take note i am not referring to the Bothan spy skill.
This would require a fair bit of good A.I to function. Nothing extreme like a caution meter that ticks away, or exclamation points bouncing up.

tell me what you guys think
