I'm sorry, but current WoW ( retail ) is very easy. Go watch Titan Savage mode (E4S) and then come back here and tell me that WoW is hard.
The hardest thing about WoW, is finding 20 folks who won't tunnel trying to parse. The time requirements to do basic things aren't a "must". We've seen in the world firsts, that you only need to be 420 to clear all of Mythic, with a neck of 60 at most. When you have folks 445+, and necks 65+ and they still can't clear the content, it just means they're bad. The only thing easier than current WoW, is WoW classic. lol
