The change to the feathers of the wind quest sucks. BIG TIME ... it was already an annoying and way too dificult quest and not enjoyable to do. The reward of those 6 coins was why ppl still did that grind and sufferable painful experience. The 6 coins felt like a reward. Also kept players in the game and invested in finishing that crappy, while rewarding, questline. So 20/10 here to add coins again. You can even leave the soulstones there too. It's fine
That questline always made me go for the 25coins ... on characters

after getting the first 2coins .... or when getting those via high RR quest reward. In my opinion, having a few ways to obtain "some" coins without the need of a Guild and GRP makes ppl interested in them and then they want to know what you can buy for those, as they will see them at some point ingame, regardless of being in a Guild or not.
IF the quest ID is the same as before, the biggest problem I see are ppl who are doing the quest right now and can't obtain those coins later again if they already got the reward once. Only doable one time.
A change to just 1 coin and making it repeatable could be fun to .... and adding the other factions in that not just empire
