I felt dirty doing it, but I finally succeeded in thinking like a marketing person, which allowed me to figure out the real reason for spells being nerfed so badly. After update 9, they want casters to have to nuke continuously to contribute to the group like they used to, run out of mana, and go shopping in the DDO store for a stack of 100 majors. 1500 turbine points, darn, I don't have that much, guess I better spend another $20 this week to buy them, then do the same again next week!
The way things are now, I'm glad that we got the change that everyone had the equivalent of a rest shrine after leaving a completed quest; I doubt that would make it in these days.
