I the subtitle is too fast i did not read what Uther transmited to emissary and the conversation with Arthas,the video when Arthas fight in Uther encampment it looks good just it passed from one scene to another.
You should make a little more the conversation Uther vs Arthas and when Uther dies show him to look ,,hurt'' and escort the villagers out from combat but escorting them.
you will have information in quelthalas about when Arthas arrived and fighting with Sylvanas? and about what the others high elf will react when he will slay Sylvanas and reach to silvermoon?
