I can understand, this is your 1st post at the wgt forum. So if you had known you could have searched & found approx. 8762 Quitter threads (some spelled 'Quiter' or Queter or Queeter ect)
I play with friends and it eliminates the quitting aspect of playing with others.
WGT has stated that it would be hard to impose penalties for quitting because there is a possibility that the person did not quit because of their score. Some just get disconnected.
I don't play the random multi-player games with many hacks or low tier either, half the time they quit & get discouraged so it's too much pain in the azz to try & finish a game(though I will say that some player will finish with a 42 or something) and my hats off to them.
But when I do look for a random game, I try to look for tour Master and above to play because I know that they have a good chance of not quitting the game.
