Please get rid of the depleted key system…

Can you guys please get rid of the depleted key system? I’m very tired of getting people into my groups and we wipe once or someone dies randomly and the tank or heals just leaves mid pull. Often I get people that leave right after the key starts and now I have to waste the time getting the key back to what it was because of a 5 second decision from someone random that I got in my group punishing me for their misdeeds… please just remove the depleted key system so if we fail we can try again and maybe if you wipe and everyone leaves put a prompt up or a message on the key that states where to downgrade if you need to. This is unbelievably frustrating when I get a 11 key down to a 7 when I get random people leaving or just leaving because of a wipe.
