I dont understand why a player looses elo points when he beats a lower elo player in a tiebreak.
For example; U have 1300 elo but ur opponent had 400 elo and he just serves well , he reaches a tiebreak and u know u loose points.
I think the serve is too much overpowered in this case.
And its strange that u loose elo even when u win.

Problem is , that when i host a game ,there are to much low elo opponents .
Mabey an idea to filter it? , so a club cant join a pro etc?
what are ur thoughts?
