Hello.
It's possible in the stats page include statistics of wins and losses?

No. Stats were so in their previous versions, but I'm not going to put that back.

Making stats on win/loss or their ratio is not very relevant.

1. It's quite easy to appear first in the win/loss ratio classement by playing a single game, win it, and never playing that game again.
2. Winning a game with a big limit of thousends of points is really not the same as winning a game with a very small limit of only a few tenths. It's not very respectful to count all wins with the same weight.
3. Winning a game with 10 players is much harder than winning a game with only 2 players, not only because the game is often longer in time but also because you have more probability to lose if there are more players. So, again, all wins shouldn't weight the same.
4. Making a classement with difficult computations to balance for the three points above, and which don't give you quickly a quite reliable, understandable and concrete idea of who is actually good and who is bad, is finally completely pointless, in the sens that it no longer has the role of a true classement. So, I decided to keep only simple classements that can be understood by everyone rather than entering in complex formulas.

Aminiel, thanks for your answer.
