Just a quick question. Considering we really didn't see much of Bolvar and i really don't know what's going on with his mind (is he good/evil both?) and considering how much the lich king and Kil'Jaeden are connected i was wondering why he didn't show up to fight him.
If i'm not mistaken it was Kil'Jaeden that created the frozen Throne and imprisoned Ner'zul into the headpiece of the Lich king, after torturing his soul. So i'm pretty sure Ner'zul at least has good reasons to get revenge of Kil'Jaeden.
Don't know how Ner'Zul and bolvar are interacting tho.
But i think it would have been cool if we had a badass cinematic showing us Bolvar finally getting up from his domain and commanding his horde of undeads into Tomb as well. After all we literally asked help to anyone during the quests to get into the tomb, why not him as well?
