No, the whole "x can decide" needs to go. No one should be dictating how the party goes. Everyone should have a say on how the dungeons should go. Not the tank or the healer or the dps but everyone.

And for that, if you can't reach middle ground, leave the party and re que. You're a tank you should get back in in an instant, that would teach the dps. Instead you played the victim card and cried in the forums and the "entitled" dps. Seriously, how do you think the community here would react? Especially with a title like that.
