They could have made it a big deal if they wanted to, but I guess in some ways it was fitting.
Cuz who even is he anymore? A human prince turned evil knight, and I forget the order but he loses his heart in the fight with Illidan and then has to fuse with Ner’zhul once the Frozen Throne cracks.
Also in the after-Anduin cinematic, I don’t understand about Kingsmourne, that wasn’t a blade we ever fought before, right? I don’t understand why they say the blade was forged with valor and honor.
Actually so it’s also not clear to me why Arthas’ soul is in Kingsmourne at all.
