Should Players be able to see their MMR in Client and stop using 3rd party Systems?

So I have replied to Riot before about my feelings that my MMR was higher than the game was registering and the Riot staff member basically claims that the MMR rating from the 3rd party places like my link are not accurate at all.

So I think it is time that Riot releases the individual MMR in the client area that only we can see so we know for sure that the system isn't rigged against players. There is no reason at all that MMR should be hidden from the player. What is your opinion?
