One interesting thing about the dungeon finder tool is that although it is supposed to be "random" it apparently gives a higher priority to instances that you haven't attempted yet. So far I haven't repeated any dungeon, except for Azjol-Nerub but I assume I was put into the same one because I hadn't completed it the first time.
At any rate, The Violet Hold was pretty cool. I liked the fact that it was blazing fast. Everything happens in the same room and there are easily-managed waves after waves of enemies.
Former WoW player, current Diablo 3 fanatic, I love the finer things in life such as PC games, beer and computers. While playing a good game is a spiritual experience, blogging about it is almost equally rewarding.
