it is acceptable if maybe once/twice an over, you get a yorker/bouncer, which is what i usually do.
however, i do disagree with people bowling 30 yorkers, but, that is how some people choose to play, as they think this is the best way to win.
If they do think that is the best way to win, so be it, but as RV as said, you can quite easily hit them to the boundary, and so we shouldn't complain if they do that.
We should bowl the way we want to bowl, and if the other player doesn't like it, then they should bowl yorkers to the other person themself
having a thread like this is negative press for this game
