Why even have 2 rings?

The game treats it like one anyway. They should combine it like the Earrings slot.

IMO Belt should be treated as an accessory and be the 5th slot. Armor should be things that are actually visible, like shoulders:

[Head]........[neck]
[Shoulders]..[earrings]
[Hands].......[Wrist]
[Legs].........[rings]
[Feet].........[Belt]
