The only thing I can think of is if you are going to sell a "open Quest on Elite" item, it should be "any quest for 3 hrs" vs a 1 shot deal... at least at the current price... spending 4 hrs to grind out points to spend to save yourself 10 minutes just isn't worth it in my opinion...
Else, nothing... I'd actually like to see more store items in game... (have been lucky enough to loot a +3 lesser heart of wood, and a medium loot gem, so far so good)
