In terms of difficulty, none of the harder dungeons in the game have a 'HM' attached to it. As far as reduced number of dungeons in an expansion cycle I guess I am not all that upset, and kind of saw it coming with their number steadily reducing since ARR. However, if dungeon releases start skipping patches then that is going to be no bueno for me.

I will say though that dungeon runs are a pretty heavy part of the game, and with their reduction in number, I can only hope that the freed up time allocation is well spent and we see and feel the results of it. I much prefer quality to quantity.
