There are plenty of slip catches when you're batting. The issue is that on pro it seems that the AI either completely misses it or middles it, meaning that they are very are when bowling to them.
I don't think anyone is doubting that there are edges occurring. There is nothing wrong with the physics, I'd go as far as saying that's it's absolutely brilliant, it just seems there needs to be some minor tweaks to how the AI batsmen play. I think if they played at it a bit better, but toned down the amount of times they got it perfectly (which is a bit over the top as is) we would see more edges and less of them being clear bowled trying some ridiculously flamboyant shots.
That however is something that they really need to take their time with that though, acting too quickly on it could unbalance everything. It's a really fine balancing act, and whilst not ideal at the moment, it is certainly better than other cricket games in recent memory were on release in that regard.
