I think I have read enough of the thread to come to a conclusion. You don't think DPS should feel entitled (and now before I proceed any further I should note that yes he could have asked in a more polite manner, and I do agree with that one) yet you feel entitled to run as you want because you are the tank and are designed to pull and control hate, you have said this many times up to page 6, so let's not disagree on that one. You should also take into account that it's the healer's job to keep you as the tank alive, so ultimately you could say the healers should ultimately feel the most entitled due to your own rules yes you control the pace of the dungeon running through, but if the pace is too fast for the healer they can just let you die.

If you just wanted to do a dungeon to speed run and skip everything you could (as you yourself said in the OP, both you and your friend wanted to be don asap) you should use the PF where you can make this plain before people join. If I am in DF and someone makes a specific request (especially pulling everything for exp) I would comply as a lot of people use DF for exp.

You also make the comment "He has a healer with him so has instant queues" Yes he did this ONCE, unless you know him and know he always queues with a healer this is not a valid comment because just because they queued with a healer once doesn't mean they will queue everytime, so yes you would just be nerfing his exp gained just to satisfy your own needs, which is being entitled.

DPS have as much right to gain exp as anyone else and to do anything as much as anyone and refusing his request is just plain selfish.
