- The DM can innovate on what that mechanic means in the setting. They can in fact innovate on every attack if they want.
- The designer has more space to innovate more interesting abilities.
Point #1 is what younger DMs seem to be doing.
Point #2 is what WotC designers seem to be doing. The green dragon statblock is more interesting and flavorful as a whole now than 2024. Now, there is still a lot of space available for the dragon block to have both, and I would, but it is better than the 2014 version IMO.
