The new rings proposed from the Desert Treasure 2 bosses are a chance to introduce something other than just straight DPS upgrades—max health scaling.
As the game continues to add increasingly powerful equipment and monsters, the maximum hits in combat continue to increase. The only way to offset this increase in the game right now are with the Justiciar amour set and anglerfish, the former of which has become a rarely-used niche option.
Now seems like a good time to do something new with these rings and add some more HP scaling.
