If you destroy object tokens and replace them with rubble markers are they still hindering. Say anyone with stealth hop on a destroyed object and still block line of fire. Thanks in advance.

When you destroy an object and replace it with rubble on the board, it is permanent hindering terrain on the map until the game ends.

So, yes, a figure with stealth could hop on that rubble and block line of fire with his stealth.

yeah at first I thought that a destroyed object left the board as if it had been used in a battle and it was a great way of getting rid of stealth hiding spots. I guess the only reason to destroy objects is to deny them from super strength and TK characters.

In friendly games I still the rule that a destroyed item is completely gone. It makes dealing with stealth a little easier without having to resort to trick shot or ultimates.
