If the guy had asked I could totally understand a lot of the 'debate' going on from solely DPS players.. but here's the thing. No tank has to stay in a que with you. It's their choice to slap on their tank class and que up, AND stay in that group. Whether you treat them like another player with needs on time, XP, or anything else or a mule that will kick you out or ditch que to find DPS with a better attitude and understanding that they're sitting in que waiting for another tank without them for that matter is up to them. Treat your group with respect (everyone involved) and awareness rather than treating them like a kleenex and you're more likely to get through the instance with fewer hitches. Lastly.. dude, you will do that instance again. And again, and again and again. Especially if you're doing random dailies, unlocking content, or just gearing for the next tier.
