You understand bad, instand of stats you will have stars, let's said for a level 8 player 5 stars mean between 55 and 59 that player should be equal with an 5 start player who is level 4 who have between 35 and 39.

So they will have stats but it will be like a level 8 team who have general quality 4 stars will be equal with a level 2,3,4... who have 4 stars. This will give you the chance to play with any friend, dosent metter what level he is :P
