Of the recipes I've looked at, the ONLY one that looks a little off is the whetstone. Having both an aragonite and an elven bismuth as requirements is pretty steep...yes, the token is good, but just saying it's "As good as an UR weapon" isn't true.
Rare weapons don't have the same upgraded damage wheels that URs do, nor do they have any special effects that most URs do, so the +1/+1 upgrade isn't equivalent.. I mean...+1 to hit, +1 to damage is in practice equivalent to just +2str for a melee character, or +2 dex +1 damage for a ranged character. Yes, it's slotless, but unlike other slotless tokens, it becomes null the moment you're using a non-red weapon. Personally, I'd suggest making it 1 aragonite OR 1 elven bismuth, while upping the dwarven steel requirement.
For reference to my involvement... I'm in the semi-casual crowd that gets a 1k order every year, volunteers full time, and does 1-2 runs at gencon, 2-3 runs at GHC. I actually have an easier time getting aragonite than I do bismuth, for some reason. Maybe that's just how my pulls have gone. The golden fleeces in relics...it's rough in my opinion, but I think I can deal with it, seeing as we've got 2 years to get materials for these recipes before the change takes place.
Something interesting just happened.
