Ever since you made the top 100 update, it seems to have negatively affected matchmaking for me. I didn't want to jump to conclusions so I observed for a little while before complaining on the forum.
I've been working my way up to Legend I, as always. But I cannot, for the life of me, maintain even the smallest streak anymore because the H option is now mostly offering "very hard" options. I used to get a fair mix, with a majority of reasonably hard matches. My win percent was consistently around 92%, it now has dropped at 85% and that involves a lot of refreshes + basically no streaks. That's a big change compared to what my experience had been until a few days ago and it has led me to PvP less than I usually do.
I've been fully supportive of the top 100 revamp as long as it didn't unwillingly compromise any other areas of matchmaking. It looks like it has. I know it wasn't supposed to so I'm wondering if something went wrong. I can't be sure that's the issue, of course. It could be just a strange coincidence. But I'm sure of this: something has affected matchmaking for me. I don't know what it is exactly but I'm not liking it at all. Any help would be greatly appreciated.
