Is this proof enough that this ability is useless? ( Divine Benison )

[Princess_Momoka]

So why take out an ability from .. 34 I think it was? only to replace it with something with the same use at level 66 with very restrictive casting ability? couldn't they just buff stoneskin to be 15% and not bother making this ability at all? What did it even do in this pic? it is so useless >< Why is it dropping in the same frame it was applied? need to delete useless abilities, even if they are gained at level 66.
