MM as far as comps go has been atrocious since the patch due to so many warriors and support queuing. Other than that, things seem the same for better or worse.
I can't jive with some of that 10,000 word essay of Srey's, though. Most of his complaints, while valid, are simply the downside of having MMR so much higher than everyone else in each mode. There's just not enough players around at his range to make the games he wants. The ones that are at that skill level all only play on pro teams/scrims and don't play the game casually anymore, or play only a limited amount versus how they did before much like our discussion about burnout the other day. I do agree they should remove the 360 limit (at the very least at a certain MMR threshold), but again, I just don't think there are enough players to support their end of the bracket. That's a side effect of him being really good, and also the fact that he spams FOTM heroes (as do a lot of the other top leaderboard players) that help inflate that MMR even higher and makes the issue even worse. Could Blizzard incentivize the game better for these people? Most definitely. But I don't think the matchmaking is the issue...if the players were there, they'd be paired to gether. Unfortunately, they've all bailed here in NA for one reason or another (more on that below).
That's the sad reality of it and not much Blizzard can do to fix it for folks like him and Fan and McIntyre and whoever else is up there above the 4k MMR plateau. There is a ton they can do to make it better for the rest of us, though.
Srey says pro players would come back to Hero League if they were matched better, but I doubt it. That's simply an NA thing through and through. EU and Korean pro players are still playing HL in spite of his complaints (that they should also be seeing). Since they kept playing, the games are less shitty cause there's more to matchmake from. It's kind of like bitching about how you don't have any money when you won't get a job...there's no one at 4K MMR plus in the queue because they got bored with it after rank 1 and the issue exacerbated from there.
Theoretically Grandmaster will fix that for some folks (and hopefully it will come soon) but this very issue he's referencing is another offshoot of why NA teams always fall short in these games and why we have so many less teams that are competitive in HOTS compared to other regions in particular...all we care about is winning, and as soon as it's too easy or too hard we do something else because #1 is the only goal. This has been discussed on Town Hall Heroes multiple times regarding the small number of NA HOTS teams vs EU and the like. It's a real thing with our gaming culture. I don't see any kind of change that would get these dudes back in here with the same regularity of other regions because those regions have a completely different mentality when it comes to approaching the game (aka, they still play it for fun even after the scrims are over).
