For Honor is a person-versus-person hack-and-slash and, as such, it is crucial for smooth gameplay for people not to be leaving matches left and right. One of the ways in which this is incentivised is the For Honor matchmaking penalty.
What is the Quit Penalty in For Honor? - you might be asking, and the answer to that question is that it's a simple matchmaking cooldown, though it does get a bit egregious sometimes.
According to Ubisoft's For Honor support page, the Quit Penalty comes into play for any players who are willingly leaving their current game session before the end of the match - this is done to reduce the amount of rage quitting, apparently.
Should you attempt to do so, a warning message will pop up requesting further confirmation. If you do decide to go through with it, you'll get a 10-minute matchmaking penalty preventing you from accessing any matchmaking playlist. Problem is, however, that the penalty also applies to all group members, should their leader leave.
It is worth noting that there exists a 30-second grace window for re-connection purposes, and that you can play story mode and custom matches even when the Quit Penalty is dispensed.
