We have two Exotic weapon sets this season and involved in the Vision collections, Astral and DragonBlood. Compare prices to unlock the vision collection steps:
Astral - 6 Weapons - 3000 Kralkarite ore + 3000 Powdered Rose Quartz
Dragonblood - 6 weapons - 360 Branded Masses
That's an 8 1/3 times larger price (in terms of map currency) for Astral vs Dragon blood. Now Kralk ore can be bought at vendors at 25/vend/day, whereas masses can be bought at 5/vend/day. Counting vendors, that's 75 kralk/day vs 20 masses/day. BUT you can get WAY MORE masses per day from Thunderhead by mining due to them being fixed nodes, and you can't get powdered quartz except from meteors, and at a much lower rate than Kralk ore, despite them being even in the recipe, which means your are gated by Powdered quartz, not kralk ore. I don't have exact values but the ratio based on my mining seems to be 4/1 kralk ore to powdered quartz. Dragonblood weapons require Exquisite Serpentine Jewels, but you need 18 total and can get about 4 per day from fixed timed events (total need time per day is only about .5-.75 hours for both meta events and the dwarf tombs), which is much less time invested than the powdered quartz.
So therefore it requires a MUCH higher effort to make Astral Weapons, despite both recipes yielding exotic weapons with equivalent collection value. And due to having a much more useful stat set, one could argue the Dragonblood weapons are higher in game value, despite being easier to make.
Items with nearly identical value should have nearly identical effort to obtain. I haven't even gone into if you want to craft all the Stellar weapons, which requires a ludicrous 10000 kralk ore, compare to only 2400 masses for all the heroic dragonblood weapons, which is again ludicrously out of balance for equivalent items (ignoring the fact that you will probably need to stat-swap the stellar weapons for most characters). We need to bring the price of Astral and Stellar weapons more in line with their value. The comparative effort needed to make these is far too out of balance.
