Since the the release of TBC, WOW has essentially followed the same formula. That formula being, increase the level cap, a hard gear reset, run dungeons until a certain point, and then raid. Rinse and repeat. My question is, maybe it is time to change up the formula. Many would say "don't change what is not broken."
However, it is clear that for a lot of people the same old formula over and over again is leading to some level of burn out.
I'm no professional game developer but there has got to be other options out there that don't involve hitting level cap and running instance content over and over. I think putting a little bit of variety and choice in what people can do at max level can go a long way in keeping people's interest. If you think about it, our characters are all forced down a single path, and it is that of the hero that goes out and destroys the big bad guy, typically via a raid of some sort. What if there were other path's you could take your character? What if instead of increasing the level cap all of the time, Blizzard introduced other means of character progression? There are many examples out there of other MMOs that don't increase their level cap every expansion and introduce various ways of character progression into each expansion. I think at this time in WoW's life, change might be good...because the same expansion formula that we have gotten since TBC is starting to run its course.
