Your Karma rating system is inefficient. Do you know STATISTICS and how it works? The sum of bad game sessions divide by the sum of good game sessions and multiply the quotient for 100. Congrads! Now you have percentage of bad game sessions. Then subtract the result from 100%. That's REAL karma. You can have 100 or 1000 good game sessions and 3 bad sessions no matter of reason and you have bad reputation. 
THAT'S INSANE that your mistake coust 10 or 20 points of Karma, but you gain just 1 Karma point for each game!
Is the goal of the BGA to avoid of appearence of new players? Tutorials not so good, and rules as well. You have to play some games to understand. The main thing sometimes to understand why the button in the game doesn't work. And you try to remember what's going wrong, cus there's no any hints for newie if you're going wrong. You can loose your carma for a day and gain it for weeks. Make a tumbler for PROs "play only with PROs" for ppl who live in these games and that's it. No complains from PROs anymore.
