It definitely wasn't interesting, but it was a mechanic that was much easier to use than the old 'hold on let me check the table for which exhaustion level did what', and was equally balanced regardless of your role/class. So it fits in as a better mechanical base, but something like... doing mechanical clean-up to a sub-system that was never used by people in the first place is never going to get the survey crowd to go OMG I LOVE THIS WHOOOOO... which they should know, but they still applied the same criteria.
