Damage is moved from Smash to other abilities...basically making your Single Target damage a little more while losing quite a bit of Smash damage and smashing less.
You smash more, actually. The Choke stack generation is offset by Enrage having a 30s base CD that is lowered by each ability that lowers Smash's CD. So you can now have stacks ready for every Smash by rotating Crush and Enrage. Rotation is almost exactly like a Rage Mara's now. Enrage = Berserk (even gives the same overall amount of rage when specced now).
