Abominations should be ungrabbable.

[BadShot]

Making the grab harm you, however? I don't think players should be punished for using one of their only strong abilities against an incredibly powerful antagonist but it's not as bad as removing the ability to grab altogether.

Well, abom isn't meant to be fought alone; going solo against an abom is suicide unless you're really robust. They're meant to be fought with a group which is typically when it's used and grabbing the abom (who is already kinda boned if they have to resort to abom) basically allows all your buddies to get free hits while the abom has to frantically try to get out of the grab, who mind you is likely panicking and we all know panicking can make you do dumb things.

Basically, it turns what is supposed to be a bloody mess of a fight into a bunch of secoffs using the abom as a free punching bag.
