Well, right. Its just that, at the heroic tier, it basically costs you two actions and has a low chance of success. First, you have to grab the target. That round you do no damage, and immobilize. Then the target gets two move actions to escape, or one to escape and one to attack you just as if it were never grabbed in the first place. Then, if it failed all its escape attempts, you can do small damage and spend a healing surge. You'd be better off using Second Wind.
At paragon tier, a feat fixes all of this. Which means that if you did craft a build that was able to easily grab someone, you'd probably just retrain everything once you didn't have to grab anymore.
All of this for a healing surge? I love the concept, and I know it can't be too great because you get it for a feat. And at level 11 it becomes decent. But that makes me sad for 10 levels.
I think the power would be more worthwhile if there were character classes that used Grab well. Hence the "see my homebrew" comment above.
