BM goes for aggressive and sometimes toxic spamming of voice lines in order to disturb or annoy the other player.
Roping goes for someone who intentionally waits every sec from his turn, no matter if he/she is done a minute ago - again, just to waste the other player's time and annoy him.
So BM = bad manners then? I had someone spamming a taunt at me once. I just muted them.
Can a player tell if you've muted them? Another time I just turned off my speaker and I could see that they were spamming a taunt at me, but it just didn't bother me.
I pity those poor souls who think that the in-game voice generator is a substitute for actual interaction with another human being. I'd be happy if it was gotten rid of, even for the voices which signal that they made a mistake or whatever.
I accidentally rope when I don't notice that my turn is still on, usually when I'm acting first and haven't used the thingy which round one starters get to use. Whatever that thing is called.
You should look at this from a different perspective in my opinion. The fact that you are matched against higher level players shows that at least you've outgrown the starting "safe-zone" of newbie players. Sure, with tougher opponents comes tougher challenge, but I believe that is always something good to have.
I remember hitting a wall last year on Rank 20. My Nil poison deck, maybe, just kept getting flogged and I stopped playing ranked matches. That time felt as tough as it was for me to succeed/fail in reaching pro rank. Funnily enough, my Nil poison deck got me to pro rank, aside from the whole CDPR not counting it because they made me unaware of how the T&Cs for that worked. Maybe it's just seasonal too, but units which disappeared from decks ages ago have made comebacks, the Geri, for example.
I'd be very careful in actually granting the community that much credit when it comes to neutrally and reliably measure things. Keep in mind, most players have their own personal interest or agenda to prove - not to mention, there are professionals designing and coding these systems for a reason. Turning these into things like classic internet forum discussions is the last thing we need, trust me. 1 out of 1000 commenters have a real clue, and even that does not necessarily moves things in the good direction.
As long as a system is affecting everyone equally, it is ok. It being flawless is a different topic, there I agree - constructive criticism and suggestions definitely help the developers.
I wasn't advocating that the community, specifically, got to say how the matchmaking algorith works. My idea was to have the algorithm open source, so that the knowledgeable could look at it, suss it out, and improve it, if needs be. But sure, community members here could contribute, if they had good ideas for the mechanics of the system.
So, I'd disagree with you about everything being okay so long as everyone was affected equally. Equality is important, sure, but if improvements can be made to the system, implement them, for God's sake.
