Next relic update in 2.38.

[Cherie]

The next step isn't too difficult to figure out what it *could* be.

So far what has it included?
1)Fates
2)Killing mobs out in the wild and more fates
3)Treasure maps and Materia
.....

So what's left? That's your answer. They probably won't repeat a step over again. Whatever it is, it probably won't make you pick up a skill you don't have (even if it might help), so that rules out fishing for example. I really doubt it would include instanced raid content due to the amount of trouble that would cause for the instance servers (remember when everyone was farming auram vale to level and it was laggy to even step foot in there?).

Things that are left (off the top of my head):
1)Demimateria
2)Notorious Monsters (I.E "the hunt")
3)Grand Company Stuff
4)Beastman tribe dailies / Rep grinds

That's by no means comprehensive.

As far as a upgrade and what ilvl it will be. Have we had any upgrades so far that didn't change the ilvl? Nope. Do we have reason to believe the ilvl won't increase? It's probably not going higher than High Allagan weapons though as they have stated they actually want people to go fight current raids and not just refuse to go. Even if it was the same ilvl, you could still get High Allagan weapons a whole lot faster if you could get turn 9 on farm. Of course, then you only have a 1 in 9 shot of actually getting the one you want.
