Low Amount Of Minion Kills In Mid Lane

I just finished a game playing good old Thresh Support. As you can probably guess I lost the match and I am here to QQ about it. It was all level 30s in the game so I am not too sure why this continues happening. Anyways what happened was we had a Lux mid on our team. I looked at their profile and they had 5 mastery on Lux, I now that really does not say anything but it at least shows they understand the champion/role. The game lasted just under 55 minutes, lux had placed only 4 wards in that entire time. Is this really how level 30 mid laners play? They did not seem to have an excuse for placing so few wards that I dont even know why they picked up the yellow trinket.

I get used to this though, plenty of level 30s seem to think wards are not helpful and I suppose they have every right to play how they want. My problem with the Lux was she only had 200 cs at 55 minutes. The only excuse I heard came from their friend/duo partner who said "laning phase is over" or something bull crap like that. How is that even remotely an excuse for not csing as a mid lane lux? It was because our Draven also only had about 230 cs at the end of the game, out farmed by jungle xin xhao

tl:dr If you have 200 cs in mid lane after a 55 minute game, you are not playing mid lane correctly. Also ward mid
