This is about the Potion Store items, the ER and the Enlightenment Center.
First off, they're all ridiculously inefective.
Second, if I pay several hundred chips in the ER for getting my HP restored, why does it merely restore HP instead of, you know, removing effects like "Needs Stitches" - After all, I just went into a Hospital, they should be able to do that....
Third, the PP restorers from the Potion Store need better spacing. The 150 chips one is 50% more expensive than its smaller cousin (which comes at 100 chips apiece) but, at best, restores 2-3 pp more. That... isn't quite OK in my eyes.
(will post more - between packing my stuff in preparation for moving out and WoW there is not enough time left for a lengthy dissertation on this subject
