If it was really as fun as people claim, we wouldn’t have called it Choreghast even when it was a required part of the grind.
The reality is that Choreghast was a long, tedious slog, neither fun nor challenging. It was just a drawn out activity deliberately designed to be time consuming to pad engagement metrics.
It was also insanely unbalanced across classes and specs, so if you were playing the wrong one, you were just out of luck. Even if you had the right class and spec, getting bad power choices meant you were still in for a slog. The whole system was a mess no matter how you looked at it.
If you genuinely think a tedious engagement farm is good design to have in a hobby, then I don’t know what to tell you. We really don’t have anything more to discuss.
