The raid is a level 11 quest and the loot is great at level. One of the main reasons people don't do this raid too often is because its so easy to level past its level range. Do the raid once and you have leveled past its level range by the time you get off timer. Here is my suggestion to get more life out of the quest and out of the loot.
1. Up the raid to level 12.
2. Have Hard setting count as level 14.
3. Have Elite setting count as level 16.
4. Have the items upgradeable like in the Reaver and Abbot.
These changes allow level 9-18 characters to raid this quest. Turbine might have to spend some resources making the change but would sell more Restless Isle Adventure packs. The same changes could be applied to Tempest Spine. Breaking the rule of hard is +1 to quest level and elite is +2 to quest level can give more life to some of the best quests.
