I've been playing with the Silithus Field Duty quests a bit. They seem flawed to me. The actual quests are okay, but I really dislike the method of obtaining them.
The quests are elite, which means you need a group to do them. However, there is no way of sharing the quest you are working on with the entire group. So basically, you get a group of five people doing something which can only benefit one person. This just doesn't seem to work.
It's one thing if everyone in the group is working on the same quest, but when each person has a different Field Duty quest, it just becomes uncomfortable. So realistically, what people do is get a whole bunch of Field Duty quests, and hope that there is some overlap between quests gained, then do the quest with the most overlap.
This seems terrible awkward to me. There should be some way to easily share Field Duty quests, so that your entire group can work on one together, and be rewarded together.
