I don't fully get what you mean but really, what does Mythic add? Yes obviously more mechanics, but there comes a limit to what is fun and what is just overkill. More advanced and complicated tactics doesn't make the boss better and the game more fun. Mythic adds things just for the sake of adding. And that is a bad thing.
But my big problem with Mythic is that it is also such a DPS race. I got the skill for Mythic, but I don't got the gear. And that sucks. I used to raid Mythic (and HC before name change) etc, but it was so demanding. I attended 3-4 raids a week in order to push decent ranks and to kill everything with a Cutting Edge achievement. It was just ridiculous the time you needed to put down, especially the gear you had to farm.
I want a scaled raid mode, with hard mechanics, like Mythics, BUT that you can enter with ANY gear and it get scaled. This way, ONLY skill is tested.
I love raiding and PvE, that's why I play mmos. But I hate leveling, gearing and farming stuff. There should be more options for those only interested in co-ordinated raid-gameplay and who don't care or like the whole mmo setting.
