Im sorry to didn't explain it better im referring to swing/ drift and other skills for bowler / batsmen
No worries man, you can set the swing however you wish to be honest but having it low means a tighter line towards off-stump which means the batsmen have to play at the ball more often. With inswing what I found was that even just 2 increments swung the ball from off to just outside leg, so to set a set a bowler who swung the ball from off to middle you would need to only assign 1 increment of inswing. Similar with drift. The other attributes spin, cut seam etc. can be set quite a bit higher but too high and you are going to skittle teams and too low and it's going to be a struggle.
So I'll use Australia as an example.
Johnson: out:1, in:1, seam&cut: 14
Harris: out: 4, in:2, seam&cut: 12
Starc: out: 7,in:4, seam&cut:11
Watson: out 4,in:3, seam&cut:10
So you can see they all vary slightly which gives them slightly different roles in the team and will also see conditions play a part in their effectiveness. Starc for example having inswing set to 4 means you have a bowler that swings the ball away from left-handed batman. While Johnson's inswing rating of 1 means that he has an inswinger that will hit middle stump which is deadly against right-handed batman especially as a yorker.
Similarly with spin:
Smith: drift:2, all other attributes 8 apart from googly which is zero as Smith doesn't bowl them as far as I know.
Maxwell: drift 0, AOA: 8
These are set low because they are only part-time bowlers. While a good spin bowler would be set more like this: Drift 0, AOA:14.
Drift is set low for similar reasons to the low swing ratings.
