I usually never post on these forums (for good reason, mind you), and having lurked in multiple threads with these types of arguments that seems to be a pretty common trend. The grammatical structure of sentences and misspelling of words on a consistent basis from the 'unique' side of the community is pretty sad, and almost reflects a 3rd to 5th grade level of sentence composition. I almost as feel these people are trolling with misspelled words on purpose to sound like incoherent trolls, but they seem to be serious...which is sad in itself. It makes it seem like the people who hate common MMO-practice features like a parser or anything that promotes a competitive and skilled playerbase are not playing with a full deck of cards.
Funny you should mention this, as I just had a discussion with some of my guildmates from WoW about this very same point. The competitive nature of WoW, combined with its massive playerbase promote a very great environment for improving personal skill if one so chooses. This is compounded by the fact that parsers, hundreds of other addons to customize your experience, and a more comprehensive logs database and SIM structure are very prevalent over there.
Then you look at this game, and there really isn't any competitive gameplay in it outside of PvP (That's a joke/discussion for another time). On top of that, this game's inherent mechanics and enrage checks promote (if not force) healers and tanks to push as much dps as humanly possible to kill something in the appropriate time. There isn't anything wrong with that per say, but then as you say they hide relevant information that makes it impossible to actually tell who is good or bad at the game. This is a pretty big failure in the game's design in itself. You can't expect a competitive raiding environment to not have a means of gauging itself, and I think that's what the OP, and others like them, seem to honestly forget.
Sorry for the long-winded response, but I definitely agree that you can't make a direct comparison of the two games. There however needs to be better tools implemented into this game to gauge inherent player skill. People can call that elitist all they want, but not everyone is made for end-game raiding, just look at WoW Mythic raids or Mythic+ Dungeons for an example. People seriously need to understand you can't create a 'super-hugbox-everyone-is-bestest-friends' environment and mesh that with harder raid content where numbers and results matter.
