Pubs MM is Unchanged since seasons 8/9
Despite all the tweaking announced I do not belive Pubs have been touched at all. As it was back in season 8/9 is still today.
You either are in a team with 2 very low level players, potentially around level 10, and in a lobby with diamonds and masters (Fake S17 master also), and have a miserable time.
Or you end up in a masters/pred/master smurf/pred smurf team and have a miserable time.
This is precisely what it was back then, 2 years or so ago.
I do not engage in Ranked, because it is the most BORING mode conceivable for a BR game. The very few times I watched ALGS matches I just went straight for a nap. But of course, this is just my opinion, as the above.
That said I see no improvements, cheaters be cheating for months before getting banned and be back in a blink. Smurfs be smurfing non stop, because their fun should trample the fun of everyone else, and they aren't even on the ban radar. No sound steps still pops up several times, far more times than acceptable.
People can still be horrendously toxic through voice chat, because who cares, right, certainly not EA since it is not monitored.
I think I struggle finding reasons to play apex, as the negatives are way more than the positives.
EDIT: The miserable experience is exacerbated by cheaters, smurfs, and unfixed bugs, all of which are perfectly within developers/publisher reach to fix.
