It's probably just us "old-timers" that have an issue with the easiness of it all. We didn't find too much fault with it the first time around, because it was new and the mentality was, "end game what?" I'm sure people that start playing now can still have quite a bit of fun experiencing the content for the first time, but we also have to consider that WoW is very raid-centric now.
Blizzard likes to push the content... even the old stuff... to allow people to actually do it. This is very much unlike what it was for anyone that's been playing since the beginning. You never hit 60 and thought, "Sweet, I'm going to go find a MC PUG!" Heh, maybe near the launch of TBC 😛.
Essentially, the first time you play the game, you're able to enjoy what it has to offer, because you haven't been "tainted" yet. Once you start hearing about these "raids" and seeing all the pretty gear, you want to give it a shot. Then you realize that the leveling process was all about getting to that one point.
