The new Aetheryte earings scale their ilvl to your level.
While we don’t know quite how much of an effect this will have, or if it could even compete with actual ilvl relevant gear (perhaps it’s only to slightly offset the fact that you’ve equipped an accessory with no real stats) could this be something they extend to other equipment in some capacity?

Perhaps not too widespread, it’d impose too much on the classic gear train and relic systems if you could just equip this ‘dynamic’ equipment at level 1 and never need to change them, right up to 80. But there could be some place for it.

How about the ring slot?
We have two ring slot options, and yet unique gear sets only allow us to have 1 of each piece, only 1 Ironworks/Sharlayan/Scaeven ring for example, so there’s always some compromise at a lower ilvl or less optimal second ring.
What if there was an exclusive, ilvl scaling Relic Ring for each job class?

Acquiring it via unique job side-quests, something we haven’t seen yet because this wouldn’t be mandatory like the core job quests, or simply via acheivements.
It could have a set of stats tailored specifically to that job (e.g. Spell Speed for BLM) to serve as a slight buffer for under-geared jobs, and as a guide to indicate what sub-stats that job should be aiming for.
