Wich they can still use, since STR AND VIT will affect our damage rating.
The way I see it, they'll change the ratio so that by going full STR or full VIT, you'll end up with the same damage output.
The STR build will have the drawback of giving less HP...like it does now, and no one cares...
And besides, current accesories will still allow you to trump anything besides Midas Savage...where it would be useless anyway, compared to lore gear or proto-Midas stuff.
