I'd never been on the site, but I'm really wondering how updated/useful those lists at wowpopular are.. especially when the title of the page says 'best choices'.
If you look a little further, you will see that the list of gear contains mostly items form an iLvl between 200 and 226, the tier sets featured are t7 and t8.
Now, this could just mean that the way they scan their data includes loads of armory profiles of priests that haven't been played for a long time, but then.. what useful information can you really get out of the site as far as what the currently playing priests actually use?

Going to double check what I have tonight against the list. But may give Glyph of Dispel Magic a look. Only really use Dispel Magic for situations where I know to use it. However running ICC with a new group and having 3 people in a 10 man turned into little oozes I realized that it can be dispelled, I know, I'm a noob always breezed through to Rotface and Festergut and never had the situation come up where I needed to worry about it, and with a Disc Priest that is still learning the ropes and has to have raid healer pick up the slack being able to give a little health back to someone is a bonus.
