I love command missions because they're a great way to level lower level classes/jobs without having to worry about slowing down other players while still learning rotations and such. Most people I know who use command missions use it for this purpose.

Can you expand on why you chose to add 2 50 dungeons to command mission?

While Dzemael Darkhold was appreciated, being a level 44 dungeon it was filling the gap between Stone Vigil (41) and Wanderer's Palace (50), there is also a big gap between Brayflox(32) and Stone Vigil(41), and a gap between Toto-Rak(24) and Brayflox(32) that needed addressing. There are also people who want 51-60 dungeons. So adding 2 level 50 dungeons when there was already a level 50 dungeon was a bit of a disappointment.
