I have now had more experience with your 3.1 patch tutsi and im here to report my findings!
Good: Much less boundries for human and cpu players, especially human. Now only well timed shots go for four on a hard pitch. Big hits have to be timed much better. Bowling still good. There seem to be less wides, but more testing needs to be done for sure. More chance of a human creating an edge or mistimed shot while batting which is good.
Bad: Not many actually, perhaps more power needed in a well timed back foot cover drive, maybe just a tiny tiny bit more in a perfectly timed front foot cover drive. Sweep needs to be looked at URGENTLY the ball goes nowwhere even when well timed. Havent been able to test the reverse sweep yet.
Verdict: A significant improvement on 3.0 although i will still keep 3.0 for when my mate comes round and we play against each other as it makes one day batting much more fun, and to some extent more realistic with more 4's. Good work mate, ill report back with more results when i can play a few tests.
