I pulled out my Paladin for the first time since ShB was released, and quickly found Shield Lob doesn't work. It's grayed out on the crossbar and clicking it gives a "cannot use yet" error. Error messages from other skills:

Cannot use yet - Shield Lob and Shelltron (without oath charge)
Not ready yet - Any skill in cooldown
Action not yet learned - Actions above my level
Cannot be used as current class - Skills that have been removed
  • Yes, I've completed the level 15 quest to acquire it (as well as all the class quests and job quests up to 70)
  • There are no quests available in the Gladiator's guild
  • I don't have access to it as a Paladin or Gladiator

Any thoughts on it?
