I don't think this is the gotcha you think it is. If I spend an extra 3 minutes in queue but spend less 6 to 7 minutes in an instance as a result compared to a single pull tank it's a win as far as I'm concerned.

And you very much can tank as DPS. I know because I've healed one such DPS after the tank disconnected at the start of the dungeon and we couldn't kick him for a couple of minutes. ¯\_(ツ)_/¯
