One more step down the path to where WoW is pure pablum for the new comers.
When you start to make everything available, and everything easier, to everyone, with no effort or cost involved, you follow in the footsteps of Everquest.
I love this game, but honestly? Blizzard is killing it with all of these unneeded, and very unwise changes.
Pablum? Unwise? You've got to be joking. It's marketing genius. Now people who have been sitting on the fence about the pandaren and the new content areas will get to see a small part of it first-hand. Then when they leave The Wandering Isle, they'll go back to the same old content and be like "Awwwwww ..."
Yeah, this isn't dumbing anything down. It's simply saying, "Here's a taste what's in store for you if you want it. And you can keep your pandaren until level 85, but you won't get to see the rest of it, of course - unless you decide you want to."
It's just smart thinking on their part.
