Curious: why are the devs so incompetent at matchmaking?

Neither is your moronic take :wink:

But the devs not communicating - oh yea, that’s a data point.
But Riot communicating? Yeah, that’s data point.

Want another?
This company managed to match a bronze against an OWL player in an arcade mode.
Yes, the video may be a bit old, but it happened.
What level of stupidity does it take for this to happen?
They are assuming independence of MMR across modes, while there is an obvious cross-correlation.
This screams either lazy or stupid to me.
This was before the scandal btw, so probably not just a skeleton crew.

It’s even simple to implement.
Use the MMR in ranked as a prior for MMR in other modes.
It’s simple Bayesian statistics.
And they don’t do it.
That’s why you see matchups like this.
And I think it still happens in QP.
