Some questions and comments:

First I love your UI, very clean. Is it shared somewhere or could you?

Question: Is there a benefit to farming the 25man trash over the 10? (IE are there BOP epic drops or something, more rep, or was it just a "wow I can't believe I could actually do it" thing? I'm curious because I'd like to start farming ICC rep with my guys and would love to know any differences between 10/25man).

Your mage is frost for: replenishment/mana conservation? Are you using a click macro (if so would you mind sharing it. I know they "pretty much" just spam frostbolt, but it would help me out). What kind of DPS is your mage doing?

Thanks for posting the video!
