Well with todays gamers just can't keep them happy SE is pretty much on the losing end any either way cause people seem to want content that can be beaten in a week or two and then they will complain about there nothing to do. So it usually ends up in one of two ways.

1: SE creates long grindy content that people complain that takes to long and boring and they unsub.
2: SE creates shorter more "fun" content that people blow through and beat and then complain there nothing to do and unsub.
