Grading system and after game grid stats

Is there any way we can implement warding and killing wards/objectives into our grade? I'm not 100% sure if towers and dragons as such already are or not. I do think this would make people try place more wards though if there graded on it. Compared to how many other people use them. I also think it would be a good way to compare and notice how much you need to improve warding and clearing wards as well. On a final note I seen this before and thought it was a good idea so Im'a bring it up again. Can we add damage done to tower on the stats also.
