Queued up for random daily and saw I had a Death Knight and a Warrior in the party. This is optimal for protection dps so I decided to Fraps it and put together a quick video. Overall DPS for the entire run was over 6400. Trash packs hover between 7 and 10k while bosses usually run a little over 5k.
Tank gear mixed with ret gear. Just enough defense to remain uncrittable in heroics. Spec and glyphs optimized for DPS.
Trying to maximize personal dps while tanking heroics is a great way to break the monotony and have some fun!
