Still with this point....
Again I ask, what's the actual problem with it?
Have you actually looked at the logs for a typical 24 man? People fail HARD in casual content just fine already. It's going to make absolutely no difference if they fail hard smashing one button, or playing tick tack toe with 4.
It's not going to make a difference in Dungeons, Alliance Raids or Extremes. It *may* make a difference in the later floors of a Savage tier or Ultimate but again. If someone can't handle a basic DPS rotation, proc system or additional dots, I'm wondering what they are doing in that content anyway.
Meanwhile if we bump up healing requirements in casual content high enough to the point where someone like me would actually notice and enjoy it? That's going to crush casual 24 man enjoyers. I find it genuinely strange that you firmly believe that any extra damage complexity will blow apart the game, yet don't seem to be capable of understanding that there are a concerning amount of healers who struggle to keep up with the minimal healing demands we have currently.
