It was a small crittic to the current situation, at contrary to certain tanks and now healers no dps can be say is a clone of other or have copy pasted mechanics and since 5.0 show the devs dont really know/care how to handle DRK design properly as a tank meaby its better move it to the dps role where gameplay diversity is well keep.
each dps is a world from each other compared to WAR-DRK and in some small degree PLD, there is no dps that have a mechanic that has been blatlanty copy pasted on execution/recast and purpose on the entire role and the dps part of the tank toolkits can and should be to synergize with themself in a unique way independently of the limitation sice compared to a DPS job for obviously mitigation reasons like ironically did in the past, and not so far in fact, basically late SB all 3 tanks where unique and have almost the same dps, the biggest diference was only DRK don't having a raid aoe mitigation and WAR having single target utility.
the question is DRK has only saw mechanics nerfs and removals instead of adaptations and improvements since HW, the job has gone for worse since that in terms of desing to end what we called today a WAR with TBN as a meme while make me raise a question, should have DRK have a better future on the dps role? being a full dedicated improved version of the HW DRK as a dps? in the end is just a theorical question not a petition not a sugestion but more of "meaby" DRK have a better future on the DPS role since is the job has suffering gameplay mechanics degradation across the expansions for no aparent reasons when other jobs that have problems or cuestinable desings has just saw improvements and reinforce they identitys specially on the dps role. what is not good is allow this heavy gameplay homogeneity when there is no need for it, tank capability homogeneity is a think but the dps part of the job don't need this at all and well of course not but if the Dev team can't make DRK unique as a tank bcs whatever problem they seems to have with the job meaby as a theory it will be better to move the job to the DPS role, i personally don't want that bcs i loved DRK with all my soul as a tank on both HW and SB but seems the devs don't know what to do with it as a tank and the current version of the job is the proof.
