It's not fun. My solo run of HoH, which was going flawless and I was at a point where I was confident of getting through it, gave me a lag spike (which I'd never had before in this game actually) and then I died because it didn't register that I moved out of the cone at all. It must have been around the time that ntt issue started.

But I don't think they can do anything about it without making the content easier. If we had multiple chances then the amount of solo clears would be far higher. If things didn't kill us, then it wouldn't be punishing enough and become too easy. It would become as easy as a dungeon where soloing it on a Warrior or Blue Mage is trivial.
