Trying to go back and do Shadowlands covenant collecting and achievements is a reminder of how terribly designed anima was/is.
I fully understand and agree with having to farm and earn your cosmetics and not have them handed to you. Shadowlands, however, is an absolutely egregious amount of farming and grinding even 2.5 years after it ended. Anima is so scarce, and everything costs and absurd amount. Full clearing every boss from all 3 raids results in BARELY enough anima for 1 of the cheapest pieces possible. That is just insanity. I won't even get started on grateful offerings because that's an entirely different situation.
Either anima costs/grateful offering costs should be severely nerfed or there should be substantial increases to anima sources. Literally just a multiplier to how much anima you get from each turn in item would fix it. instead of 35 you get 350. Instead of 250 you get 2500 etc.
