I am not sure this is needed.
The reason why so many people use HP rings is because this is a permadeath game.
Such it has always been.
The only time when DPS rings have really ever been considered viable by many people outside of PPEs, at least in my experience, was… well… never.
Amulets were once THE ring to use, because they helped you evade death. Once they got removed, people often used a ring like Pyra to ensure survivability (before UBHP and in a time when def was more valuable, the 4 def was considered better than the 40 hp you get from exa hp) and then over time UBHP became more popular as endgame lessened the importance of def.
As Unibro said once when asked about Spectral Cloth Armor, “your DPS is zero when you’re dead.”
Survivability is the defining thing people look for in gear often because people don’t want to lose their hard-earned characters. There are of course those that play for a full DPS set or other sets like mana or wis sets, but they are definitely rarer because the majority of players (myself included) are not good enough to just rely on their dodging capabilities for that playstyle.
