wouldnt need to even affect gameplay at all, but it would be a non verbal way for folks to thank others for good performance. If it were to affect gameplay copy Hearthstone and make it reward the other player who was commended. this will naturally encourage others to perform well. add like 500 Dockets per commendation so its noticeable but not massive, call it a commendation bonus.
