On my journey to level 90, the new priest talent Divine Star was what I found myself looking forward to the most. When the ability had first been announced at BlizzCon 2012, a few commenters suggested that the spell would probably behave just like Prismatic Barrier, an ability from League of Legends. Prismatic Barrier allows your character (specifically the character Lux) to throw her wand to a targeted location, shielding any allies standing in the wands path, then return to your character. When the wand returns, it returns to Lux's current location, as opposed to the location where she was standing when she first threw it, thus allowing you the potential to heal several different players in the two paths of the wand.
The prospect of being able to do this in WoW had a huge appeal to me because it required a certain degree of raid awareness that went beyond just staying out of the fire. Using it to its full potential would mean knowing where everyone in your raid was and positioning yourself in optimal locations to get the best of it. In League of Legends, these types of abilities are called skillshots because they require good aim and timing to be effective. I loved the idea of having that in WoW.
