My only concern is Living dead and Dark Mind. Both gathering dust
Living Dead skill is not good. It is the "IN CASE OF FIRE BREAK THE CRYSTAL" Sort of scenario. It completely draws the healer's attention, it requires to set up a macro for the sake of letting the healer know "Hey I am going to die unless you pick up the healing", and it is not something you can use strategically like the Paladin HG. You only use it when things are looking grim, and by that point chances are ... you are going to die 3/5 times if the healer is not able to catch up. It is just not a useful proactive skills, it is just reactive for when shit hit the fan compared to the other tanks that can use their level 50 Skills in a more versatile manner for a wide variety of scenarios, and if you are tanking properly and the healer is doing its job, the level 50 skill will sit there like a pretty decoration rarely being used. Whoever is saying Living Dead is fine... he or she is not playing a Dark Knight I am pretty sure
Dark Mind ... never used it AT ALL.
By itself tanks are unpopular. I need to wait 30 minutes to be able to queue for dungeons compared to the 3 seconds wait when I switch to DK, talks about the class popularity in general. My point is as far as theme goes, yes I get the "Dark Theme" of the Dark Knight, but might as well make a boring class more interesting by releasing many of the the impediment or mitigating them and with this I include WAR as well. Just take away the "Death" part of Living Dead and the "Not Moving" of WAR. By the above reasons, living dead is useless by itself if you have a competent healer. The dying factor doesn't make it any better.
