Pretty fun dungeon. I really liked the swirling spiral walk up to the boss with waves of mobs.

Crafted from the same mighty vines as Razorfen Kraul, Razorfen Downs is the traditional capital city of the quillboar race. The sprawling, thorn-ridden labyrinth houses a veritable army of loyal quillboar as well as their high priests - the Death's Head tribe. Recently, however, a looming shadow has fallen over the crude den. Agents of the undead Scourge - led by the lich, Amnennar the Coldbringer - have taken control over the quillboar race and turned the maze of thorns into a bastion of undead might. Now the quillboar fight a desperate battle to reclaim their beloved city before Amnennar spreads his control across the Barrens.

I always thought that RFD was one of the more unappreciated dungeons. It's actually got a great variety of mob types and keeps the run fresh, even if it can seem a bit long. Lots of bosses too.

the RazorFen instances are two of the best and most under-rated adventures one can have in Azeroth.
