I think it was deliberate.

"Player abilities that grant Major Savagery, Prophecy, Brutality, or Sorcery now grant both of their respective versions (such as Savagery and Prophecy) in efforts to reinforce the accessibility of hybrid stat gaining.

Note that player passives and consumables that grant the Minor versions of these have not been adjusted at this time, in order to preserve class unique power contribution for coordinated groups."

It does lead to some slightly weird stuff. For instance, on my magdk, I've now swapped all spell dmg enchants on his jewelry over to weapon damage as the pasives give him minor brutality rather than sorcery. Yes, it actually works.

Stamplars it seems are going the other way because of the illuminate passive.

I'm still working through my stamsorc; there's a lot do do with him - I think stamsorc gets the most out of this change by far. I hadn't even picked up this one
