Chaos Zakum, how hard is it?

I thought HT pendants cost that much because of DC hackers making runs hard and HT being level 180. CZak isn't as hard as HT and you can do it on more channels(?), so it should / could be cheaper.

I don't know about not being as hard as horntail, but it is definitely much more taxing. 12+ people are practically required to kill chaos zakum within the time limit (at least before people start making ridiculous potential stuff), while 1-party horntail runs can take as little as an hour and a half pre-potential. Also, horntail gives a ton more exp to the point where it's actually not bad exp to train off of it. I don't know about how much fun people think chaos zakum is though, the dispels and seds at the arms are annoying, while the bodies are just as boring as regular zakum.
