The whole reason I stopped watching Season 2 was because I came to a sudden realization.
Log Horizon seems to be best whenever you marathon it. I found if I missed a week of Log Horizon season 2, I would enjoy the 2 episodes way more than I normally would. I didn't watch the first season of Log Horizon until it had finished airing, and I was just absolutely engrossed in it.
So I am going to marathon up to where it is now, and then wait until it finishes before I finish it.
