I think this question is hard to answer as tastes are different.
I love WoW. I loved Classic-Wow, I loved BC and I also love WotLK. Admittedly I am what gamers call a "casual player" so my opinion doesn't count that much as long as you aren't a casual gamer too. *g*
edit: indeed a lot of gamers stop playing wow, cancelling their accounts; many gamers claim the game to have become boring and without any challenges.
