Final Fantasy VII: Rebirth

I hate to feed this idiot's thread but couple points on the topic:

Crafting ring (HQ) is 2% chance of synthesis material loss, not 1%. If you're talking about doing dozens of synths with materials worth upwards of 3-5m/ea and sometimes up to 7 or 8 materials, it can (probably) add up quickly. I'm not willing to sacrifice my time or gil testing these synths without the ring to know exactly how much, but it's a unique effect you can't get anywhere else. It is literally BiS for crafting. Keep in mind that if you're farming Ody/Dyna for 20m/week and then make gil crafting, you're getting 20m+profits, you shouldn't consider that 20m as substituting for the profit, because you can do both. Which would you rather have, 20m, or 20m+?

I think the FC effects of Weatherspoon are basically useless since it also has quick cast on it, so unless your lua is detecting that you quick cast and putting in potency gear (I'm not sure if they CAN do that, I don't use GS), you should not be using weatherspoon for the vast majority of spells you cast (anything with a midcast set, essentially). It's still a really nice ring for light WS etc, but I wouldn't consider it a FC ring at all.

Movespeed ring covers move speed for some jobs that don't have any 18% options, but if you have an 18% option for your job(s) I think the meva/DEF/DT you gain by wearing a ring slot movespeed is completely insignificant the vast majority of the time. You have to ask yourself: how often are you getting hit while wearing move speed gear? How dangerous are those hits? I would argue that these are extremely niche situations or irrelevant situations. Most people aren't dying in their movespeed gear...ever? It's still a fine option if you primarily play job(s) which don't have access to 18% move speed otherwise, I guess, but also consider how important movement speed is in terms of completing content...is it REALLY important that you move 6% faster when walking around town? For actual content (Sortie) where move speed might matter, Bolter's roll can cap your movement easily.

For my part, my characters have crafting shields so I have the crafting ring for both, but barring that, I think Janniston, Thurandaut, Weatherspoon, Vocane, Shneddick are viable options, depending on your job layout. It's impossible to say which is best because it depends entirely on which jobs you play and how often. If you play all 22 jobs on a regular basis (read: nobody) I'd say my opinion would be Weatherspoon > Janniston > Schneddick > Thurandaut > Vocane > anything else.
