wow has gotten too complicated for my enjoyment. I still have my pally in the gaf guild and stopped leveling at about 47. That was the point where I didn't want to deal with all the extra abilities. I miss simpler times in vanilla.
Maybe I'm lazy, but I really think if blizzard wants to continue the game, they need a reboot somehow. Something where you wouldn't exactly lose your previous gear or levels per say (only when not in vanilla through MoP), but where your characters go through some kind of portal/rift, to a completely new world, and it's like starting over. So in essence, it's like a new game, but you're still continuing on with the same characters that you have spent so much time with leveling through previous expansions. It would be a completely new story that isn't bogged down with trying to continue previous lore, balancing issues, and the continuance of tacked on abilities for the sake of making another expansion.
So you'd still be able to return to Azeroth at any time, where your toons would revert back to their max level, complete with all of his/her abilities again and items. This could be similar to when TBC came out and you lost the ability to fly when going back into the vanilla zones. I'm sure they could twist everything into making sense story wise. But with each new expansion comes more and more abilities, levels, items, and balancing. The game is getting top heavy imo, and would be nice to have an expansion where somehow everything is reset and things are fresh again. Simplicity in fewer abilities, but depth in how you use them, with a completely different class system, abilities, and mechanics.
Each class would be altered when switching over and not only start at level 1 again, but become a completely revamped class at the same time, but similar role to the former. Or blizzard could come up with some new level scheme if starting at one again sounds stupid. It should be a whole new pursuit to end game. And at some point during the leveling process, you might be able to gain access to some of your previous items like pets and possibly mounts.
I think this would also be good because they could cut out the previous content for brand new players, so new players wouldn't have to purchase all the previous expansions if they didn't want to.
I've been wanting to throw my thoughts out to gaf for a while now. Not that it's a new idea or something that other people haven't already thought about. I just want to experience the newness that was starting at level 1 in a completely new world. All these expansions lack that experience.
