I suspect that part of the confusion of memory is that since clarity is a level 29 spell and it used to take players a considerable amount of time to level there are many enchanters (even that started on launch day) that would never have realized clarity wasn't in game until after launch because when they finally got to 29 it had already been added in...not to mention that folks simply didn't even know the names of their own class spells yet, let alone the buffs they wanted to ask for by name from another class.
