Haha, I've been playing a custom format too recently - 1992 world cup - 15 overs PP, then five men out, two new balls.Played another ODI today, this time bowling as both teams on PRO/hard bowling difficulty, Dusty/Soft/Pristine pitch. Note that I'm playing with 2005 rules: Only 1 ball, 5 men allowed outside when not in a powerplay, PPs are first 10 overs then two 5 over PPs when the fielding team chooses (although I can't quite get this to work right and currently it's first 15 overs is a PP then one PP whenever you choose). The powerplays proved to be the key, when I was bowling as India I thought might be able to restrict them to around 280 but I left the PP until the end and got pasted in the last 5 overs to allow them >300. When bowling as Australia I used it in the middle overs and India lost 4 wickets during the 5 over spell which blew through their middle-order and basically put them out of the game. Despite a good partnership between Kaif and Pathan they couldn't get close to the RRR again.
I'm not sure what difficulty you're playing on @wasteyouryouth but Pro seems perfect for me for ODIs at least. I definitely wouldn't bother playing above Veteran, the AI was atrociously bad on Legendary in DBC17.
Bonus Zaheer cleaning up Clarke with some beautiful inswing:
I'd had similar results though on current ODI format.
I'll give it a go on Pro, I use fully auto fielding anyway, I'm not sure what differences there are besides the timing windows for catches. On DBC 17 I never noticed anything different between difficulties beyond that either.
Cracking dismissal too.
