The thing is actual bowling of good length deliveries mixing it up with seam swing pace and all the real world cricket tactics also work in DBC and are as effective if not more than the above mentioned methods. I can guarantee you that cause i have even had some amazing test matches online were i have been able to out fox or my opponent has been able to outfox me very effectively without resorting to any of the cheap rock paper scissor above.
But makes it 100 x more engaging to play than Rock paper scissor tactics mentioned above, often even though i can play these deliveries even win against some of these jokers without even using their techniques back at them[often they are that bad they just think preparing for these tactics will make them good and plain old cricket of left armer outswing followed by a full inswinger traps them or a couple short pitch followed by a sudden yorker ], The RPS methods just causes more boredom than leaving a 100 balls in a stretch 'yawn yawn Yawn boredom' and the people using that are tossers who dont love cricket a bit, if you just want to win online go play some nonsense FPS or WOW, in such a small pool of the supposed sport we love its a pity to see so many tossers.
I mean im some one who moaned about warne opening in second innings by AI how the hell would i like it for the so called superior Human when he opens with warne on a green pitch and goes to bowl half tracker after half tracker, even when i can play it by playing late its just plain dourness to spend my time.
Hence the only way to have cricketing enjoyment online is just stick to playing friends and people you know have a good pool of them, if not just join some league with good rules.
Also if at all you are looking for randoms, go for people looking to play longer formats anything over t20, custom test formats like 3-5 wkts matches etc are mostly good and with save match will be a better bet than playing 4-5 fifers.
At the same time i would say rage quitting is as bad as the RPS tactics, at worst atleast forfeiting is a better thing if you cant see it though. If you take a match its your part to see it though, if you don't like the bowling use forfeit. Most quitters would be batting first and quitting bowling or when the opponent is close to victory though.
