Ranked placement system seems to be flawed?

Almost all of my matches in diamond have 1-2 people out of 8 players going like 1/20. They're just getting absolutely obliterated and probably aren't having a fun time. So to me that says somehow the placements aren't doing a very good job at getting people to a rank they should be at.

I do not know if this is caused by a lot of people 4 stacking and possibly being carried to get a high ranking placement. Maybe the mmr system needs to take into account individual score more? But it does make a lot of games generally unfun when your team or the enemy team has someone that obviously does not belong in that rating.

This does tend to happen when new competitive games come out, it takes a while for everyone to get to their appropriate rank. But some of these matches have such a massive skill disparity, its not even close. Yes I realize its just a beta, but I hope with the full release the ranking system does better.

I think the biggest issue is that ranked placement is highly based on your casual wins. Yes, casual, and only your direct wins. It doesn't take into account whether you did well in those games, or whether those games were against bots, or anything else.

Most people place plat 1-2, even if they go 0-5 in their placements. It seems like the average amount of wins you get hitting level 15 (especially considering 1-10 is almost entirely bots) is enough to get you into plat, even if you don't even remotely belong there
