From my experience I consider this patch extremly good (compared with like how it was before patch). Netcode has the same quality, so don't expect have better connection with people you had bad connection. But now Ranked Match can be played decently, and that's the point for me.
Now you can filter your room with "2 and up" or "3 and up" or "only 4". I played with "2 and up" and I was playing around 1 hour and half just against people with 2 or 3 bars, even one of 4. Of course, all of them from my country. Now with patch, those who "had" 2 bars but they were laggy are 1 bar now (ping is calculated better), so they can't enter into your room, the filter totally blocks 1 bar people. This means you can play ranked match without having to fight against 1 bar or laggy 2 bars. Only playable matches with 2 and 3 bars, now. But, unfortunately, this means less people to fight too...
I'm glad to have Player Data fixed too. My player data says that I played 860 times with Mature, but only 180 with Mai... T__T
