What would you add / change to the FATE system?

[Barraind]

Raise the sync level by 2-5 levels on most fates.

Add a small amount of poetics / uncapped current tomestones as rewards.

Slightly raise bicolored gemstone rates on completion (20-24 per).

Add a currency like bicolored gemstones to old fates.

Add some old dungeon drop housing items, out-of-the-way orch rolls, mob-drop only crafting ingredients (Yak milk, steppe milk, dhalmel saliva, bear fat, ect), Amber-encased vilekin, and a few odd minions to the new gem currency.

Fates of the appropriate levels produce light for relics.

As someone who capped class levels, capped all the shared fate areas, and still needs a handful of gemstone-bought items, I would regularly do a few fates here and there if I could progress multiple things while doing it (my last couple ARR relics, finishing collections of stuff, earning currency for tradeskill mats), but giving me rewards I'm better off paying gil for (350-400k gil vs 30 fates is not a win for the fates side) and nothing else doesnt do anything for me.
