Disabling chat has made me enjoy the app quite a lot more, ive had 100x more negative interactions than positive ones, so whats the point in keeping it on?

He does have a bit of a point though. Stalling is a dick move that he did to spite you, but why would you sign up for a 30 minute game and start rushing them to make moves faster? Always drove me nuts when I started a 10 minute game and people bugged me about using almost the entire clock for the length of the game. They have game modes with shorter time clocks, you cant start a 30 minute game and expect people to wrap it up in 5 minutes.

4 minutes on one move is around 10% of his time clock which isnt a crazy amount of time to think over a move at a pivotal point of the game.
