I know about that and I also agree with you a little bit! Just to let you know something:
I am a high rating player as well, before I use 1 of my nicks and get about more than 400 points, When I first come to the lobby, I played with everyone that challenge me, no matter what their ratings are. But a few people are very funny, if they are luckily win, they will runaway without saying anything! You must understand that high rating players need to be very careful when playing with low rating players because if they win, just get very small points. But if they unfortunately lose, they lose a lot! Like me, last time I win for 4 matches with 3 different players and get 16 points from them. Then the 5th match I play with a (red) player, 0 points. That is a very cursed game and I made about 15 scratches and lead him to victory, made me a lost of 27 points. After that, he run away without saying anything. And it's very hard to get the points back!
Although you may say that this is a game and points are not important. Well, they are not, but we join this game for fun and in my opinion, I always want to play with someone better than me, such as: Mr SkunK, Willie Thorne, Spence... If I don't have enough points, they don't want to play with me because if they lose (unlucky), they will lose a lot! That's something nobody likes!
Beside that, I also hate those people always hanging around and check others' info to find if something was wrong and report it to banned them because of jealous! I didn't say it's not right, but sometimes they put their big nose too deep in our a$$, report everyone that play with tha same person many games!!! I think that was stupid!
