I suspect we'll see at least some minor nerfs to the Anima stage in 3.25, if they continue with the idea that the stages before the "raid-level" end-stage for the weapon in the corresponding patch cycle should be easier to acquire (like they did with the i170/i200 stages).

First and foremost, as others have mentioned, the tomestone costs will probably be reduced somewhat, and we might see corresponding reductions in the number of Precision Gordian Parts required as well. Drop rates for Luminous Crytals may very well be increased, too. Toward the end of ARR, they started getting more generous with nerfs to the earlier stages so people could more easily catch up, and I think we'll see some continuation of that trend now.

I wouldn't expect significant nerfs to the Anima stage until 3.3 at the earliest, though.
