Your favourite Burning Crusade instance?
Quel’Danas, added in patch 2.4, it was first outdoor zone added via patch.
I like Blood Elves, I like how their areas are nice and colorful. But instance itself is really nicely made, the music is awesome and it looks really really good. Also if you do this on heroic mode last boss, Kael’thas Sunstrider, can drop Swift White Hawkstrider mount. Which looks like the Blood Elf racial mount and as a Alliance it’s really cool to have 🙂
Also Orb of the Sin’dorei can drop from every boss on heroic difficulty, it disguises you to look like Blood Elf 🙂 I still haven’t got mine.
