As of now Relic is designed to be the Starter Endgame Weapon to get players into Endgames and to get those endgame gears and weapons.
As of now I'm waiting to see how their progress balance out later but for now it seems they're keeping Relics depended on RNG during the start to make certain not a lot of people will hit Coil turn 9 too early until 2.3 when Relic ilvl 110 is released with CT 2nd raid for alternate ilvl 100 gears.
By 2.3 we should see a increase in RNG drop rate for Atma or it is completely removed because of ilvl 110 Relic Quest.
Currently by average a causal person will take around 1 month just to complete all 9 books done anyways to obtain Animus after they obtain Atma.
