Group is MMR for within your rank range.

This guy is ruby but he's only playing other high rankers who play alot and are better than him, if this ruby guy somehow reset his rank then started playing again in low rank he would be diamond fast then drop off diamond at high ranks again because he's not good enough.

You're retarded and this basically means if you're diamond it doesn't mean anything unless you are high rank diamond.
