Fine Crusader Ring question

I've noticed as I'm doing the quests, my eqiup inventory continues to keep the old rings in there. Is it necessary for them to stay in my inventory, or can I just drop them?

Drop them.
Useless PoS.

The rings near the end give 1-2 atk. But if you have better rings already, they're worthless.
I disassembled my rings.

Just don't drop the Zeal Ring you get at the very end of the quest line. It gives a +2% exp bonus (though it's completely glitched right now and doesn't work).

You could also extract the rings.
