World of Warcraft is boring. A new expansion won't change anything. You do the same shit you did the previous expansion...and after hitting endlevel you start raiding or start another twink...great. Ahh wait now we have something to do...we can do crazy pokemon battles *yay*
Seriously, it gets easier and easier you don't need any skill to kill or clear anything...Tier sets are obtainable without raiding, perhaps you know get them just through online playtime or something. Just a boring old concept geting worse every expansion. It was a great game once, now its boring shit.
