I am a player with an often bad internet connection, mostly due to the country I live in. Lets get that out of the way...anyways, when my internet starts dcing me, it will often cause me to lose games I had in the bag by causing me to skip a random turn, which is incredibly frustrating and can make the game unplayable when my internet isn't being stable. My suggestion is to pause the player's turn counter when he dcs, that way he comes back with enough time to actually do his turn. In other words, while dcd, the counter to surrender starts dropping just as it does now, but the dcd player's turn counter pauses if its his turn.
If someone DC and the opponent asks for FQ, it will auto-accept for DCed one, so if you are not winning you can get out of jail for free
Why do that when you can sit for 3 minutes and take the win? I'd rather gamble on getting a win than FQ and get nothing for the time I spent.
