The new MMR matching system in ladder is not good

It seemed really great in the beginning when you don't see the opponent rank and you think "cool, I'm matching against opponents with my winrate"... but I reached legend since yesterday and I thought of playing some meme decks (as you do in legend). But then i got bored and I started to play seriously again and since I'm legend I can see my opponents rank. I've been destroying diamond 10 and 9 opponents and possibly made them gave up from ladder. And it doesn't feel good at all. Why am I not matching up against legend players for so long? This guys got no chance. I would not have felt good knowing that I was matching a good legend player if i was diamond 10.
