Well if people are being stubborn/close-minded for whatever reason about letting certain jobs brew, the trade/gifting system would be nice since the cruor can still be put to use instead of being a dead value sitting in server memory. I'd much rather be able to help my friends in some way with the cruor I have rather than listen to complaints about how they are out of it. Of course other uses of the gifting system, for example, could be helping out someone who just returned to the game and just got the new expansions and is trying to collect all the maps and cruor bought atmas to catch up with their friends. It doesn't have to just be about giving people cruor for brewing, although that would most likely be the top use for such a service.

I've tried to talk to them, but they are of the mind that Aeolian Edge isn't damage efficient enough (kills per brew) compared to their weaponskills on NIN and SAM while under brew effects. And yes, this includes factoring use of proper atmas too.
