Friendly games - Friendly Championship

Hi Nordeus, can you please detail what exactly did you change in the way that outcome of Friendly matches is decided? This wans't part of any release notes also i guess it was a server side configuration not a client version fix since this is happening wince like a week or so.
To detail what is happening... you are now able to lose agains much weaker opponents (and I am not talking about 1 stars weaker I am talking about 20 levels worth of difference).
Thanks in advance
