This small change will stop queue fishers instantly.
My main is a DPS but I tank most of the time in dungeons to evade this problem, and agreed, the best solution would be to remove all visible indication that you will (or won't) be joining a party in progress and place the 30 minute wait for any type of instance drop except for full premades.
