Paladins deflecting Shattering Throw?

[Pitbite]

How can this happen? It's my first time seeing something like this, it's happened a few times now that ret paladins have deflected my shattering throw. It just makes no sense since it says in the tooltip that Shattering Throw is supposed to remove any invulnerabilities.

I main a warrior full cata, and never seen that happen before I stopped doing PVP, which was like 2 months ago. might be a new bug. try to replicate it by dueling a paladin, take a screenshot and report it on the bugtracker

[-Nevermore-]

can confirm. happened to me a few times. not a new bug.
