Well in a way all those specs still exist.
The d scim spec is still there in the form of the smash ability, the d spear spec is there because every style has a stun ability and for d dagger the combo abilities are similar.

All forms of combat and skills are still prevalent.. They're just masked with mainstream updates. Take away all the glitter and it's still there -- just in forms of different names and keybinds. However, yes, there are some aspects that were completely changed/removed like the Wildy toggle.
