I personally was really upset by Kelsier dying, he definitely was my favorite character in the book, with Dockson coming in second.
Vin... I don't know, I didn't mind her near the end of the first book, and I didn't care much about her at the beginning. And after starting the second book, she's reminding me more and more of Faile and Egwene. Whiny and annoying rather than core to the story.
I did enjoy the fight with the steel inquisitor, and I was expecting, and quite happy, about Marsh's return, though I had hoped Kelsier would find out about it before he died.
I never really saw that Lord Ruler wouldn't be the hero of the Ages, but I picked up on a Feurochemy and Alomancy link, mostly whenever people talked about the Lord Ruler being immortal, I figured that it would be kind of anticlimactic for him to be anything more than a man, and when Sazed spoke about storing your age, that's when I connected it for the most part, I just attributed it to being another metal in Allomancy though, not Feurochemy.
Sanderson has hinted that a lot of things in the first book (this coming from the side-reading on his site), about the Lord Ruler will come about in the third book.
During this read of the second book on the other hand, I'm really excited to read more about Marsh.
And as cheezy as it sounds, I hope Kelsier comes back!
