Why is Maws Lifegrip passive effect so puny compared to Steraks fury?

Steraks makes it really obvious about it's offensive capabilities when popped making the user massive, meanwhile Maw gives you like a 5% model size buff (did you guys even know it made you bigger?) and is forgotten about when the shield is gone

Lifegrip should have the same model size buff as Steraks does, to fulfill my Hulk fantasy
