I read this:
Allagan tomestones of philosophy are no longer obtainable.
Please note that any Allagan tomestones of philosophy obtained prior to patch 2.2 will not be lost. All trials and duties that formerly yielded Allagan tomestones of philosophy will now offer either Allagan tomestones of mythology or Allagan tomestones of soldiery.
Then immediately went to buy whatever i can before maintenance, After that when i continue reading:
The NPC Auriana in Revenant's Toll will now give players the option to exchange Allagan tomestones of philosophy for Allagan tomestones of mythology.
I know i was hesitating, but We should have a time refund for tomes at least
