The balance in bowling and batting in DBC17 was way off for me. With batting the slightest mistime or misdirected shot can end in a wicket, with bowling I rarely ever felt like I'd get punished. I always thought that poor footwork or timing should lead to wider deliveries rather than a reduction in pace. It was almost impossible to bowl a wide sometimes even in one day matches.I've always (quietly) liked the idea of a "dice-roll" style mechanic to bowling whereby you actually don't "select" a delivery type at all. You select a length prior to delivery and the rest is up to a dice-roll based on attributes and game situation. For example, it would be "easier" to bowl yorkers in the final few overs of a "close" match, the AI batsman would then have a higher chance of "reading" your deliveries and come down the track to you. Based on the attributes of the bowler you select, the dice-roll determines how effective your attempts are... I don't have nuanced language to describe it any better but you get the idea.
Likewise the difference between pace bowling and spin bowling (because of the turning of the stick to impart spin) made those styles feel equally unbalanced. I'd sooner be able to choose a delivery type and then have a modifier (e.g. hold R2 to go for a big turner or big swing ball) that then causes a minor penalty in accuracy, with that penalty reduced the more confident a bowler becomes.
