Some of those who post use the textbook definition of rigged as you stated, but many use the word to express strong feelings about the fairness of matchmaking.
I mean sure, I prefer to call dogs cats and cats dogs but the reality is dogs are dogs and cats are cats and if the world revolved around my preferences that are wrong weād all be lost.
I have no real interest in being accurate to ramblings.
If you think thereās an all encompassing matchmaker that:
Analyzes deck win rates
Match decks with counters as appropriate (thus poisoning itās own data)
Manages to do that while players go in and out of sessions, change cards, change classes, and still matches everyone in those 10 or so seconds
Simultaneously can be beaten by luck (thus further poisoning itās own already poisoned data)
Simultaneously can be beaten by skill (more poisoned data)
You just zigzagged between Blizzard being competent, incompetent, competent, and incompetent again, without even touching on the technical aspects of it.
Check history, find who are the people who have logically contradicting worldviews with persecutory undertones, and then come back to reality, where you already do a good job of making yourself look foolish
If a player plays worse than almost all players online, Blizzard canāt do much about it; theoretically they could try to match them by waiting more but waiting for multiple minutes is probably worse; and itās not a rare scenario to play worse than most online for a few reasons.
It reminds me of the reverse scenario; a player who goes Legend 1 (or CAN go Legend 1) probably plays better than almost everyone online; Blizzard canāt completely prevent them winning >>50%.
And all the people who are at the top 100 Rank every single month is just pure coincidence. And how some people manage to make it into the master tournaments over and over and over again. Yeah, another coincidence of course.
