The difference between 108 and 120 on gear slots when you factor in that in some types of magic players can get 600+ spell power is not very much really and 108 can be found in better spots like lootgen hats or rings..
Kind of the overall theme of post update 14 is a miniscule increase in power with weapon and gear whereas there is a major increase in power through levelling and experience i.e. the destinies and epic levels. It really dampered my enthusiasm for running the druid quests in update 15 and will damper my enthusiasm for running the update 16 quests likely. It is also why so many players quit ddo. Not a strong reason to run quests repeatedly and the devs do not put out enough quests to justify the not run quests repeatedly approach.
