I actually like the ground slam with the regular wookies. First off, If you'd pay attention you'd notice that a successful hit with it regenerates a little bit of health. A knocked down enemy gives the wookie a chance to actually successfully 1v1 somebody. So you get a knockdown + a little bit of health back = most likely kill.
@C-townladiesmanSomeone on the forum here made a post about all enforcers and mentioned as a strong downside of the ground slam that your opponent gets faster up than you, thereby decreasing your chances to win again.
Sure, your opponent loses health due to the slam but if we compare this to the the stun gadgets of the ARC Trooper and the CC that allow you to shoot with your higher rpm guns at your opponents, beginning at the moment while they're still being pushed, it comes off comparably weak.
That's from the post at least, I don't really play the wookies often except in Dreadnought attack/defence and never really need the slam, so I haven't tested that out yet.
Slams is only good if you have a team with you to take advantage of the situation quickly
