Sorting the quest journal by difficulty instead of order received might be a VERY good idea to resolve that quest journal issue. I have heard this a lot, difficulty knowing which quest to do first. As a note, there should be a short line indicating the next goal in the quest either above or below the details. Sure, it's nice to read the full details of the quest, and a shame that players don't do so, and not having a summary of goals will pander to this. However, insuring they understand the quest is more important.
