Thanks for your feedback.
While I agree that the current system is not perfect, you should also take it into consideration, that it is supposed to be a casual online game, not a serious competitive event.
The main purpose of the rating system, is to give the possibility of our players to find opponents with similar skills.
The current system does a pretty good help in this, as sometimes you get the hammer, sometimes your opponent does. So it is more or less square at the end.
It would also not help to play at least 2 ends, as you can then blank the first with the hammer, and then do what you can in the 2nd (so basically the same as if you play only one end).
It is also not the best to allow only 8 or 10 enders, as a game would last a couple of hours then, which is not something all players are looking for.
I am pretty sure that if you wish to play longer games, you can find some opponents for this ( I have already played some 10 enders). Get to know each other, look at the other player's info, which shows if he/she plays only one end or more usually.
If your opponent has to leave after one or two ends, just simply look for another ;)
