Why Can't We Ping Our ms In-Game?

Before I begin I would like to make sure that people know that this is simply my opinion that I believe should get at least some attention. I am not trying to say, in anyway, that League is in any way terrible in discussion. Thank you for reading this. Why can't we ping our ms in-game? I have not found a way to ping my ms in game. If there is a way that i have not found out, please tell me. I believe that if Riot made it possible to be able to ping our ms, that many people would not blame other's for feeding or AFKing simply because there are some people who do say that they were lagging as an excuse for trolling. If it is possible that we can ping our ms, we can better communicate with our team to show that it is better to not fight and more than likely feed due to a high ms which make's very difficult to play without dying within the 30 seconds of a fight or even the 10 seconds of a fight. Hopefully this does reach to somebody who can show this to somebody who can actually make this happen or make this suggestion to a riot team that decides on changes in League. By The Way this is my 1st discussion that i have posted so if i did make any mistakes, please try to help me to make it better. Sorry if it is not great discussion
