Why are people constantly trying to appeal to the lowest common denominator?
If you read your spells you know what you need to know already.
If you want to Mythic raid you can do your own research.
Why does Blizzard need to implement a guide in-game for each of the specs when you can type "arms warrior" into google, click on the wowhead or icy-veins guide and poof, you got your basics down.
I can tell you the moment Blizzard would try to force people to do mechanics all the time during leveling the same people here would be like:
"But i don't wanna do mechanics, i play to chill, what is this elitist bullshit, boohoo, boohoo, give me mythic gear for normal dungeons".
