I am aware, I probably should have elaborated a bit.
the working parts of the entire book are now running a 3+ by default, therefore the case for the shrine to work got narrower
if it is not a normal wound the shrine is rather useless on non-cultist units
except the Slaanesh prayer they read a lot less impactful than the previous ones
flexibility is gone as the shrine is locked into its prayer through its mark and it seems that new lists will now bring multiple marks
considering that "everything" is more expensive, there are fewer points to spare and the shrine in its previous glory was the first thing that was cut from current lists, even with all its upsides (although it is a bit cheaper now but why not add two extra cultist units or another hammer instead, you would have to save a lot of wounds to make up for an entire unit)
the army seems faster than before, it might be difficult to keep units in range (although in all fairness is 18" is pretty big and will only be a problem in later turns
At least it returned to its previous point cost.
I am not arguing that everyone should melt their shrines down. It still seems like a reasonable unit but it most certainly does not strike me as a winner in the new book.
