dislike behavior of the dialog box w ...
When a player lags enough a message will pop up informing you of this and will give you the option to disconnect from the game. If you click and hold the mouse button down on this option, then drag the mouse away from the button and then release the button, it will still act as though you clicked the button. This is contradictory behavior to how several other dialog boxes behave in the game. (Other dialog boxes act as if you didn't click the button under these circumstances)
I would like to see it not act as though you clicked the button under these circumstances, to allow a rash player to undo the initial decision to click the shiny button that suddenly interrupted there experience.
Also please make it so that Enter key doesn't accept the prompt. When it triggers your instinct is to try to communicate with the other player and find out wtf is going on, so you press Enter to chat... and then it disconnects... and then you put head > desk.
Oh and lastly, can you make it appear indefinitely instead of only for a incredibly brief period of time? That way the players can decide whether or not to give up instead of the system deciding for them... I just lost 2~ hours of my life on an Endless map and had internet failure and got no reward at all. Would have been awesome if the game for the host & client just remained paused until a connection could be re-established instead of waiting a set amount of time, especially since it's all peer 2 peer as far as I can tell..







That "laggin'" window appears as well if your co-op bro has alt-tabbed.
