So, what's with the lack of Machinist in DF?

[Velhart]

If I que as a tank and see 2 machinists or 2 bards I usually leave the group and try again in 30 minutes depending on how fast they kill the first encounter.

I have not come across one person in DF dungeons that can do higher DPS than myself on MCH. The point is, it is the player that delivers more than the job. I would take two good BRD/MCH in a dungeon over two cruddy BLM/SMN any day.

Also, BRD and MCH do really good damage, especially in raiding scenes (assuming you are not having to use MP song/turret too much). In a equal skill level/gear with other players, we are only slightly behind. I keep up with the other people in my party just fine.

That being said, it is a large understatement that a lot of MCH do not know how to be efficient at the job.
