i feel sorry for you.
Shadow, Storm and Stone doesnt say the Mogu killed Y'Shaarj alone. Especially since at the time the Mogu were afflicted by the curse of flesh. But anyways, Ra-den was the one who led the Mogu into that fight. They didn't do it alone, they had the power of a Titan Watcher with them.
Im reading chronicle atm. So far the Titans story was change, Sargeras's story, as was the reason why the old Gods attacked planets. I know what their stories originally were. I've been playing this game since TBC, but I've been a fan of Warcraft since Orcs Vs Humans, and I've been a huge lore nerd. I've been getting more and more pissed that they keep changing stories.
