(Current) matchmaking serves only one purpose

Whenever i start playing everyday and more than few games a day i start having the same experience (without exceptions) , game starts to be extra snowbally and almost every attempt of teamplay suffocated by the enemy, my mmr gets down but enemies don't seem to get any weaker(but on the contrary)- i dont claim that teammates i get are bad,not at all, but somehow it's nearly impossible to play anything as before .. then again i will get bored by monotony of losing , make a pause and after week or 2 games will again be somehow balanced(one way or another) until i start to play regularly

Therefore with all the experience i have on that matter my conclusion is that "matchmaking " serves best ,if not only, to make players addicted to the game

anyone else ?

P.S. bad english
