The talent Protector of the Innocent currently heals yourself two times if used in conjuction with Light of Dawn.
What this means is, if you cast Light of Dawn on more than one person Protector of the Innocent will heal you twice.
Now, the wording is a bit fishy,
,Code:"Casting a targeted heal on any target, including yourself, also heals you for 3337 to 3839."
so this might be intended, but having the talent proc twice doesn't really feel like it's the intended purpose.
