I'v had this on my mind for a while now and thought this would be something interesting to discuss..
Right around the time Cataclysm ended.. I had been thinking about how many changes and altercations WoW has gone through. I used to be an avid player in both aspects of the game (PvE and PvP) but since MoP hit, I have become way less interested in playing. Now I know this is only my point of view, but I feel as though the game has just gone through so many changes that it makes many people miss how "simple" the game was. I say simple in the sense that PvP wasn't as intricate as it is now.. and Raiding was not so complicated. To be good at either aspect, you had to work hard, practice and be an all around active player. During Burning Crusade and WotLK.. although some things we're unfair and overpowered, the game was just better. plain and simple. Aside from a year long ICC-fest, and Death Knights in PVP obviously.
It's hard to explain the point I'm trying to make.. but hopefully some people can relate to what I mean..
The game has changed too much for it to be enjoyable.. I am not saying changes are always bad.. but I feel that the game just needs a giant review and needs to, in other words "defrag" .. (for those of you who don't know.. allocate it's priorities and get rid of the useless things that make the game boring and complicated)
Hope this makes sense.. I tried!
