Viability and comparison of tanking classes in Heroic Progression Content.
I have been having a heated debate within guild lately conserning the apperant lack of viability of one of the tanking classes when it comes to progression and raid resources. I will not name the particular class that I feel is lagging behind enough that I have asked this guild member to roll another class if he wishes to continue in a tanking roll so that the conversation will not be shaded immediately by opinions from players who love that class.
I am looking for opinions from players who have completed the current content on which tank classes if any are considered by them to be a drain on healer resources through excessive damage intake or tank classes that you feel are more prefered because they are quite the oposite.
I know that it will be hard to avoid an opinion fest so I am looking for empirical evidence to be brought to the table.
