And that's where WoW Challenger comes in. First up, the thing I was most impressed with, is that they've got Gold Medal video for every single dungeon, in their tactics section, but also accompany that with a full written walk-through. What's more, a helpful gnome spends the entire video with you providing useful tips for dealing with trash, tricky pulls, you name it. They even provide maps with the best routes to maximize your speed through the dungeons.
But there's more to this great site than just video, they also have tips for gear, flasks, food and potions, professions, and extra items like the Restorative Amber item from the Klaxxi that is vital for casters, or Rod of Ambershaping, or the G91 Landshark. In all honesty, even if you're not interested in Challenge Modes, you should probably check this site out. You might learn something, I know I did!
