Every week i play Trials on all 3 characters. This week i figured out the hard way that if you get disconnected during trials, your mercy doesn't count, thus giving you an automatic loss. I don't know why trials is set up this way, but it bothers me. This should be fixed to where a disconnection counts as the Mercy.
My best guess why network disconnections do not count as a "loss" is to prevent players from purposefully disconnecting their network to avoid losing. Losing a match "fairly" is the only way to register a loss.
