I'm hoping that the titles don't end up attached to the FoS. Earning the title was previously a req. for the achieve/FoS, if the FoS grants the title from here on out then it will never go away (i.e. earn Glad once, be forever Glad).
I'm assuming the damage was originally supposed to be a negative side effect to using the ability. The fact that it ended up breaking CC was a fun oversight by Blizz that wasn't game breaking and added skill to the class, so they kept it. Just hope it doesn't get changed to increase dmg taken instead of DoT.
