Why is forfeiting discouraged? In chess resigning when the game is over is considered good etiquette. Why waste the opponents time when the result is decided? I know I personally am always happy to see a forfeit, as are several players I know.

@ Glint these are the missions to be auto completed with time.
and I personally do missions in dt's with 4,4 deck.
in elo, only thing i want is to win.

In elo forfeit is normal, unless it was a 50-50 in the third round, in which case some players will leave and others will just play it out
