Dunno if this is a Wowhead mess up or something a dev at Blizzard goofed on, but
Starlight Conduit - “Wrath, Starsurge, and Starfire damage increased by 5%. Starsurge’s cooldown is reduced by 4 sec and its mana cost is reduced by 50%”
Am I missing something here? Starsurge doesn’t have a cooldown, nor does it use mana. I look higher up in the War Within talent calculator at Starsurge itself, because I want to see if it’s changed how it’s used, but no, it’s still using Astral power and it shows no cooldown.
