So, someone wanted help with a Basion Nymic, never done one before, and he had 5 Ichors and the rest of the group didn't.
So, the group had the 5 ichors to conduct the ritual, but it wanted 20.
IMO, for content that is supposedly difficult, and you want help, the game should incentive people to want to join up with people. On one hand not getting the 5 ichors and being able to do to the content (for daily) is a little easy, on the other hand it makes it so much harder for someone to find a group if the rest all require ichors. This mechanic will not have much longevity if everyone needs ichors.
