One other possible solution is for side quests to have a recycle time something like 45 days where they reset and can be done again. This also allows people who want to level multiple magic/war classes to avoid having to level by fate grinding alone. Also on a side note Dark mater is WAY overpriced you have to wear your gear below 70% or so before its a cost savings not counting the investment of leveling the trade skill in the first place and that most likely any end game class would need 3-4 + level 50 trade skills to repair all of there gear and the gear of the trade skill classes.
