Are achievements putting too much pressure on players?

I'm not in a WoW place right now. I tend to move through phases of being a casual or a hardcore player. It depends on the content available (such as a new patch) and my workload. I did most of the Noblegarden achievements but now Children's Week is here I suddenly feel burnt out. Except for a quick romp through Gun'drak with my guildies last night and a pit stop to pick up my orphans, I've been strangely distant from Azeroth.

The thing is, I know precisely why. It's the pressure of achievements and festivals. Let me be clear, no one is making me do these things but me. Last year I enjoyed Children's Week because it was my first time doing the Outland version, I got rep, money and the smug feeling you get from taking a cute Draenei orphan around to see her heritage. Now all my guildies and most of the other people on my sever are frantically going for the achievements and, in some ways, it feels like the holiday has been cheapened a little. Being so close to Noblegarden probably hasn't helped either.

But it makes me wonder if I'm the only one? Right now I'm a casual player, but do you think the point of these holidays has been lost by the desire to get a Violet Proto-Drake?
