What are some character interactions you wish you could have seen in-game in WoW? Or atleast seen more of?

In terms of stuff we didnt see in WoW, I really wished we could have gotten a conversation between Varian and Arthas. As far as I know, the two of them were friends as kids. Facing lich king arthas would have been very personal for Varian. Another thing (also involving Varian) was a conversation between him and Turalyon. Just them reminiscing about Lothar and the "old days" or something.

In terms of stuff we did kind of see but wish I could have seen more of, I really would have liked a deeper look at the relationship between KJ and Velen. Perhaps a flashback of a conversation around the time when Sargeras first approached the Eredar. My headcanon is that KJ thought that joining the legion would genuinely be the best way for his people to survive. Seeing a debate between the two of them about something like that would have been amazing.

Anyways, what conversations did you want to see (or see more of)?
