Countless users noticed a change in terms of competitiveness. Some of them even have a router which shows where they connect to. Those players can prove that the way they are getting matched, has been radically altered since the patch. Now let's just assume that nothing changed in terms of matchmaking... Why is the lag so incredibly intense then? Why are melee hits not registering etc etc. If matchmaking isn't to blame at all, then something else went horribly wrong.
