Okay for the 20th time I'm not expecting blizzard to change the game. They said they might add another spec it makes no sense to add another melee dps spec it does make sense to add another tank spec since there is very little crossover between classes with ranged dps specs and the ability to tank. It also thematically fits since you could use the dragon knight concept. Also I don't spend time waiting I run my own key and fill it quickly due to io and at this point just running it at 15 since I already got my unlocks.
Now articulate why it is you are so against adding a tank as the third spec what on your mind does it hurt and what makes adding another healing, melee dps, or ranged dps spec better to a class that already has two of the three and a game that is massively oversaturated on the the third
