Honestly, I don't really quit, and when I do it is typically because of latency related problems, and when it isn't that, It is probably due to the match taking way too long. There was one time where a match toke pretty close to 5 hours for me and my friends to complete (and come out victorious), and we weren't camping either, we were actively engaged in combat trying to get each others eggs, and trying to send each other to the pit of despair.
Interestingly enough I am not a fan of OP Items and Half Health, and before I get the cops called on me for having an opinion, here's why: OP Half more often than not, for me at least is to see which team can rush the other(s) the fastest, combined with the wicked cheap normal gapps makes it not that fun for me. Another thing is that I'm not a fan of having the exact same thing happen every single time (OP Half is basically rush to victory from my experience), and I can hear the keyboard clicking away about how eggwars is the same thing over and over, but while that isn't technically false, it isn't as obvious. I love being given a problem or situation, and being told to solve it, and when I am playing with friends in eggwars (very likely to have at least 2), we love to strategize an attack to take out the other teams, hence the reason we enjoy OP Normal, Double, or Triple, but not half. I hope you all will accept my opinions, and not have the cops summoned to me.
