Wards placed in post game

I find it weird that wards placed shows up in detailed match history, but not on the post game screen (in either the grid or graph portion). From what I can tell, it's the only statistic missing. I noticed this when my ADC said I didn't ward when I placed 30 of the lil' buggers, so I'm really only salt over that.

Still, it's odd it's the only one I see missing as a numerical statistic. Is this because of a client limitation or a lack of demand?
