You only need cover to hide, not to stay hidden.
Wrong. You have to maintain the conditions that allowed you to make a hide check.
Example:
1. Larry the rogue crouches behind a trash can. Bob the wizard then walks into the room. Bob rolls Spot vs. Larry's Hide, and fails.
In this case, Larry is hidden.
2. Bob the wizard then Disintegrates the trash can.
Oops! Larry's cover is gone, meaning it is impossible for him to Hide, meaning Bob sees him--no roll needed, Bob just automatically sees Larry.
Nowhere in the rules does it say need to stay behind cover or in concealment to hide.
You quoted the rule yourself: "You need cover or concealment in order to attempt a Hide check."
No cover? No concealment? No hide check. Otherwise, a person could step behind a tree, make a Hide check, then step back out into the open--and still be hidden.
That makes absolutely zero sense. And completely obviates the need for the supernatural ability Hide in Plain Sight.
All you need is the distraction or something to break up your silhouette, and you can hide.
You also have to be unobserved. If you're observed, even casually, you can't hide. So if Larry, after having his cover removed and being spotted, decides to walk into some shadows... sorry, no dice. He's observed. Larry has to first completely break line of sight to Bob. He could run around a corner, or go into shadows that provide 100% concealment, or whatever. But once he's spotted he's out of luck.
The actual roll tells how good you've hidden yourself, and what the spot DC is to find you. If you rule it any other way, then there is no reason to put any skill points in any perception or stealth skills, because the fighter with +2 spot is going to see the rogue with +26 hide every time. Now how much sense does that make? :\
Er, of course a fighter with +0 spot will see a rogue--if the rogue is in the middle of the room with nothing to hide behind/in. That just makes sense. Hide is a mundane skill, not a supernatural ability. I think what you're looking for is Hide In Plain Sight.
