I finally got a chance to run Halls of Reflection last night. Actually, this wasn't my first attempt, I had it pop as a random a couple of days ago as a heroic and I wasn't ready for that. That was a pretty fast and humbling experience, but last night I queued up for regular mode just to see what it was all about and to learn the strategy.
There is a lot of grumbling about this instance, claiming it's too hard. My brief heroic experience will confirm that it is hard, and running it in normal mode you can see how challenging it can be, but it is also incredibly unique and fun. I love the storyline and how it plays out. At the moment it's probably one of my favorite dungeons. That may change after a bunch of heroic wipes, but for now all of my memories of Halls of Reflection are positive. I'll check back in once I complete heroic mode.
