Ooh, imagine if Ye Huo had gone too! Not that it would have made any difference in the end...

I would have liked to see that! I'm not sure having one more person on their side would have helped them fight Ye Zun, but it would have been cool to watch. Or, if three of them are enough to keep Ye Zun occupied, having an extra person might have enabled them to do something else (like getting Zhao Yunlan out of there).
