I'm surprised you did not take advantage of the situation to suggest possible changes to Fortification.
I never understood why the feat respec was gated by dragonshards. To me, a respec is something you want to give your playerbase to adapt to rule changes and to recover from mistakes made while learning the game (or experimenting). If that is the goal, then limiting the access to it by requiring a rare item seems counterproductive. Even less when the respec could instead be used as a moneysink to take some of the virtual currency out of the game.
If there is a concern about frequency of use, a timer or a cost that increase after each use (with a cap and lowers when not used after a certain amount of time) could be used instead to ensure that the players don't use it too often (if that's really a concern or a problem).
This, by the way, also applies to Lesser Reincarnation.
