This is the rule I follow.
This. Likewise if I queue with a friend and an emergency comes up that rips me away longer than I expected, I'll send them a message on discord asking them to let the party kick me outright if I know it'll take longer than ten minutes to resolve. It sucks, especially if I queued as DPS, but I'm not about to waste the time of other people simply for my convenience. When it comes to solo-queuing I'll just apologize if I simply think it'll take too long and leave the party. I'd rather they get a chance to refill the slot than wait on me.
