So as the title says, the only time it appears to matter if you get all 9 Relics is when you are doing the campaign expiditions for the Companion Drops.
Since M16 has hit every single run I have lead or been part of has collected all 9 relics but we are rewarded from the quest giver with anything from garbage blue through Alabaster to decent purple.
Surely if you want us to collect all 9 give us at least Alabaster / Purple only as I have heard of people running without collecting any Relics also getting the exact same rewards we are getting.
It may be 100% working on your Dev only super secret test server but please come on live and say hand on heart that the rewards are in fact scalling dependant on the relics collected, because right now it does smell like another Oops M16 bug moment.@mimicking#6533 @nitocris83 @Devs
