Timeout penalty in casual mode

I don't believe so? You mean like, if the game crashes and you can't reconnect in time if there's a penalty for it? 

Ah! Then no, there's no penalties of any sort in unranked (at least on PC) so you're free to quit as many matches in succession, whether your banner expires or not, as you please. It's nice they kept it that way, really lets you skip the tedium of playing every match out and simply focus on whatever your weeklies are. 

@Daze623 perhaps. Understandably, there are people who play casually just for fun, but they do still want to win their games, and thus having no punishment system for leaving is essentially a slap in the face as for the most part more teammates = better chances of winning. 

However, you'd also have to understand that there are a ton of people who work 8 hours a day (maybe not so much so during these times) who just want to play as much as they can before they have to sleep. Being dead and watching fish flounder isn't quite as fun as actually playing. There's also people who once again have limited time to play and want to grind out as many objectives on their battle pass to make sure they hit the 110 end goal. You can't respawn teammates if you're dead, you can't get knockdowns if you're dead, etc. etc. Being punished for leaving because they have responsibilities and limited time to play doesn't seem fair. If you were to punish them, how could you justify it, and why? 

In my opinion, I highly doubt Respawn will put a penalty in place for leaving in casual games. They understand that most of their player base is exactly that, casual. 

@pastaclownHow can I justify punishing constant leavers? It's easy when you quit the game you ruin the game for your teammates. Lets say you get knocked down and you immediately quit then your teammates win the fight now the game is harder for them. You try to justify it by saying people want to grind challenges what about people who want to do knockdown and revive challenges? So now if they want to do those challenges they have to play rank just so people don't quit every time something happens to them? That's not fair for those people too specially if they hate playing the campy playstyle that rank brings. I feel for them if they can only play for a few hours everyday but that still doesn't justify ruining games to try and get the challenges. The ends doesn't justify the means.
