What is the lack to the Monolith?

Write non-obvious problems, please. No need to write “not enow content”, all this is obvious and correcteth over time.
Perhaps going to Aberoth is too fast/slow? Perhaps the Harbingers are too easy? Or the players build their builds too fast and they are too accessible? Etc.

So far, most often I hear only one is “quickly bored”, but no one giveth specific reasons for this. Maybe someone seeth something that the developers don’t see? Let’s help and try to figure out what’s wrong with the Monolith in addition to the lack of content.

PS By the way, a review will be released soon - Raxx’s video about season 3, this will also be interesting.
