[@Blu] Ok, so I changed up the average strength to chucking the car door like a discuss "with significant effort." I also double checked some references and found that slate (the stone you suggested) has a hardness rating of 5.5 while steel is only one point harder at 6 to 6.5. So considering how close they are I altered it from tearing steel like paper to tearing through steel with serious effort. Do these slight alterations in word choice create an acceptable nerfing?
