Depleted keys don't reward a chest at the end. there is no endless loot loophole with mythic + on just one key. if you fail the timer, key gets depleted you still get one chest.
if you fail the depleted key, you just wasted however minutes of your life the instance took.
if you succeed in a depleted key, you dont get loot just a new key which isnt depleted anymore.
