I wouldn’t say I was heart broken... but I felt sad when they finally killed off Arthas in that Lich King cinematic. He had a great story arc since Warcraft 3 and I was sad to see him go. I knew his story couldn’t last forever.... but I still felt kinda bummed. I didn’t feel anything when they killed off Illidan (I originally thought they killed Illidan during BC before Legion). But Arthas felt different.... hard to explain...
