Oh god, stop with the "L2P N00B, we had it hard in vanilla" attitude.
Here's the thing. I do love WoW, I've played it for a long bit, had some fun times raiding, and cataclysm is fun, except for the healing part.
Resto druids took a hit in cata. The mana thing wasn't really ever a problem, it is easy enough to handle. The thing is they took away our mobility, gave us watered down spells and just made us boring.
