I've written an article for Tankspot with my thoughts on the currently-released updates in the WotLK beta. It mostly talks about the questions that the Protection Paladin faces heading into the expansion, and tries to answer them to the best of my abilities.
The article can be found at Tankspot if you'd like to take a read.
EDIT: Direct link here. It's still on the front page at the time of this writing as well.
