I don't mind fate grinding the 12 atmas. I don't mind myth farming 13500 to upgrade an Atma weapon to the Animus version. But I do mind that a ilvl110 Animus weapon is underpowered in comparison to other weapons of the same ilvl.
Atma version (ilvl 100) => same damage/stat levels as an ilvl 90 relic or ex primal weapon
Animus version (ilvl 110) => same damage/stat levels as an ilvl 100 weathered weapon
There should at least be an appropriate reward for the task.
Edit: Noticed that I had a typo in the title. Should be "underpowered"
