It is a bit strange that Blizzard is implementing this. Rio is a pretty fleshed out tool. It goes a long way past giving you a score. There's no reason for Blizzard to make their own tool unless they might be thinking of creating a queue finder for m+. This is their 9.3 super feature. Think about it. Quite often Blizzard creates a super feature towards the end of an expansion. LFD, LFR, Flex, Mythic dungeons.

You not having the capacity to understand a tool doesn't mean it's toxic. What is toxic is mis-representing yourself for content when you know you have no business being there.
