I DO NOT wish to start a game when the enemy team is already inside the capture zone.
It is extremely frustrating to keep getting spawned mid-game.
Yes, there are people who quit the game but it drives me crazy when I take their place when the game is already started.
In my opinion the initial stage of the game is the most important and it is a part of my playstyle.
I absolutely refuse to play games that have already started and the only thing this results in is me just leaving.
This matter has been raised countless times already.
The devs should make some kind of a work around or give players the option to chose whether they wish to be spawned in games that have already started or not.
Another suggestion is to give players another option to chose which maps they prefer so they leave less games.
I see where you’re coming from, but in my experience, some of those battles can be really intense and fun. Like an underdog fight or something.
I like this idea.
Something along these lines were suggested in the recent roadmap, so we can only hope the devs are cooking something with it. 
I have spawned many times while the control point is being taken, and several times after it’s been taken. Kind of makes you feel like your in a football game and come out of the locker room fired up to play, and find out it’s in the second quarter already and you’re behind on the scoreboard. 
Maybe give players the option to specifically join in progress games and give them an XP bonus for doing so, like join random team? And prevent it when that option isn’t checked? Or something like that
Idk man, I fight enough underdog games with the average intellect of teammates already, I dont think it would be too much to ask for it to not just throw me into an already lost match, like I never leave a match early, but thats just a slap in the face, leave it as an option for those who wish to matchmake fast I say.
