Not the right place for this topic but:

In the beta people complained about tanking classes being able to lot Need on DD gear, so SE changed the system so tanks can only Need on gear meant for tanking, physical DDs can only Need on gear meant for physical DDs and mages can only Need on gear meant for mages. So even if your current class can wear the item that drops from the chest, if the item isn't suited primarily for their role, they can't cast Need on it, only Greed.

Its not like I've checked if every single piece of equipment is working as it should, but from my experience the system is perfectly fine as is.
