Yeah Alt Shot usually isn't too bad, players mostly stay even if it seems like an unfair duo(you really never know)
It's just stroke play where people say WAHHH I HIT IT IN SAND ON HOLE 2 I QUIT.
For me personally, I wouldn't have a problem with people quitting if they just gave you the XP for the original game. If you have a 4 person game and 3 people leave on hole 8, you get 1 person XP even though you've wasted all that time with 4, it's extremely annoying. You started as a 4 person game you wanted to do 4 person, you shouldn't get penalized XP because Hiney McWhiney decided they don't want a bad round.
