This was more along my thoughts and reaction as well. I thought the love blooming in The Final Empire was quite believable, but after that I only saw flashes and as a whole wasn't moved by them as a couple.
I suppose this was influenced by me finding Elend increasingly distasteful (which I do lament) through the books. Far too self-righteous for my liking. He is a very very good character though.
Vin on the other hand I connected with immensely, and it wasn't the fact she died that made me angry, still makes me angry (I'm burning up right now phwoarrrr haha :P/>/>/> ), is that I thought she would make a perfect god (Especially for Preservation) with all that compassion and goodwill and belief in others.
And suddenly she was gone, and it fell to Sazed. Sazed, who who had hardly felt or understood love or relationships until Tindwyl (Which I found very believable :D/>/>/> ). I guess you could say the same for Vin but I believe she had much more of a sense for this.
But I suppose it's all in my opinion on what would make a good god. Scadrial couldn't be remade without Sazed's metal minds, I know, and he's probably going to figure into things in the future but.... maaaaaaaaan! :lol:/>/>/>
Please excuse my semi-rant lol. I'm new here. Hi! I've never actually felt so strongly about a character dying in a book. Emotions are supposed to be irrational, right? :D/>/>/>
