Rdf debuff

I think it would be a fantastic idea to add a debuff like deserter to people who miss or intentionally troll as the tank or healer for the RDF mechanism. Im suggesting maybe a 3-5 minute period where the person gets a deserter debuff and can no longer queue for RDF if they miss the queue regardless if they are doing it intentionally or not. If you are queuing for a dungeon you are basically agreeing that you are ready to participate as a group member and help to complete the dungeon, and it is not fair to the others who have waited in queue sometimes up to twenty minutes to just get their hopes up when some resto druid wants to troll the RDF system and queue for tank and instant decline and queue for tank and instant decline and repeat this over and over. There is really no downside to this idea because the deserter buff is so short that anyone who accidentally misses the queue will only have a very brief waiting period before they may queue again and the trolls will only be allowed to troll 1 time per 3-5 minutes. Thanks for your consideration!
