Just finished a crucible match a couple minutes in with the other team doubling our score. By the end of the match we were down nearly 100 and had only 2 guardians (including myself). Looking at the stats afterward, there were 8 players on our team that had quit. And this isn't a one-off, with recent changes more & more of the matches I load into are already in progress. When players quit, it makes the game nearly unplayable as missing a player puts a team at a severe disadvantage. The penalty needs to be severe enough (several hours at least) that a player will really thinks twice about quitting.
