I suspect it is situational, dependent on the batter, conditions and other factors. Last night I was bowling to England with Crawley and Morgan in and they were leaving plenty. But the team were three down, it was a grassy pitch, bowlers confidence was probably up. I had a period of six overs without a boundary and I wasn't doing anything different from what I'd done before and after that. Then they got to about 20 runs and started to go aerial rather than piercing gaps to get their boundary per over.
Conversely, I've had fewer leaves at the start of an innings (which, is ideally when a good batter would be leaving) when bowling to Warner and Harris. Crawley is much taller, than a player like Warner, so maybe where the ball is pitching and the height it reaches the batter, could be another factor at play in their shot selection.
To be honest, I'm less concerned about batters leaving than I am about their persistence in scoring boundaries with such predictability and the entering T20 mode when they get past 20. Crawley and Morgan went from playing what felt like a fairly balanced manner to batting like it was 400/3, not 100/3.
If they leave three in an over (I had them leaving more than that - I think I counted five in a row from Crawley) and then you launch it over long on I'm don't care about the number of leaves. The construction of innings is a problem that spans each format, I think the AI players in too predictable fashion. But these things aren't things have cropped up overnight, they've been issues to a certain extent for several games.
I don't know what has changed that might impact AI batting in the last month or two but my bowling experience is really not different to how it was when I started. The lofted shots does seems noticeably different.
