I'm dusting off my DK after having not played him since DS. I'm doing what every self-respecting WoW player should do and researching best play strategies, gearing, talents, etc.
I was honestly surprised to see several sources, including Icy Veins, say that Runic Corruption is a very bad talent for Frost. What I can't understand is: Why?
You don't have to micromanage unholy runes to ensure you only proc deaths or frosts. You don't have to press anything, you literally can't screw up using it. It's a flat increase in valuable resources, all of which you use as Frost.
I get that "mathematically" the other two options can work themselves out to be worth more runes over time, but that assumes perfect play. Is that really the only reason everyone says RC is bad? Or is there something else about it that I'm missing?
