They could have nerfed all of it from what I remember.
The thing with Grasp, is it slows and its a damage over time, put Acid cloud into it, and you have more damage, all while your dogs are chewing on the bad guys. So while the damage is small, it does stack with everything else in the area.
Also, blowing up your dogs is like a last resort, but it was a viable tactic back in the day. Also the Cooldown on dogs seems longer now than it was before.
