Have played a fair bit now on PC and patch 2 (xbox).
This is a great game, but it is hugely let down by the AI field setting when batting and the extreme rarity of AI edges when bowling.
When batting, the AI field setting is simply not fit for purpose. Ok so they start with slips now (FC) but they will be moved out quickly. After a few overs there will be a field change every ball. Hit a leg glance, there's a deep square leg. Cover drive the bext ball, the square leg will be moved to deep cover. Hook the next one... Deep cover moved back to deep square... And so on ad infinitum. God forbid you play two forward defensives, you will have a silly mid-off and a silly mid-on. I don't see that it's an issue of tweaking, it's a broken system, that needs reworking from the ground up. In the meantime they should work out a few fields and restrict the AI to those until they have a proper AI (hint, not one of them involve no slips, a silly mid-off, short mid off and a short leg).
When bowling, the scarcity of AI edges negates the excellent bowling control system and still makes bowling a chore. I don't feel there is any element that bowling to a plan will work. I have also been experimenting with different pitch conditions - to be honest neither batting or bowling seems to be different on any conditions.
Hopefully the AI edge issue can be resolved via tweaking, so you'd hope to see some improvement on that soon, but the AI field setting is more of a concern.
