I would like to say that I would use this, not just ignore it. Using a matchmaking system like this will reduce frustration, increase player skill, and make the matches more fun.

It's hard to learn playing against far better/worse players.
It's becomes dull playing against far worse players and frustrating playing against far better players.
Matches with = skill levels create a situation for max potential fun.

And I have no problem with abd.

Just my 2 cents
