I've been in max level groups groups with a MCH that never used Hypercharge, a DRG that only repeated True Thrust -> Wheeling Thrust, a GNB that only used Aurora, a SAM that literally just hit random buttons, etc. That is who normal content is balanced around, and to be honest that doesn't bother me at all. I'm fine with harder content being relegated to harder modes. What concerns me is watching core job design be simplified across the board to cater to those types of players.
