I think you cut out too much from the duel scene and it lost gravitas. Originally Daelin stripped off his armour, ignoring the cries of his family before Tyrannistrasz mocked Daelin about if he would dare to attack even if he stood there, Daelin had no expectation for surviving while doing this. I think not having those three things are what makes it less meaningful, aside from other padding like it being the most awesome stab he made as a father or all the people finding it unbearable to watch Daelin's assured demise.
