Ok well I'm in danger of going into some detail on this subject, possibly involving comparative footage from different iterations.
One easy starter - are you somebody who watches the bowling action closely when batting? Did you get a bit tired of the repetition of bowling actions in 14 and 17? Did you wish you could bat against bowling animations captured from actual international players?
In this respect things have improved markedly since DBC17. Some posters here regret that BA put so much work into animations and would rather they'd worked on other stuff instead, but I don't think anyone is likely to argue persuasively that the bowling animations of previous iterations were better. For me it's a key part of the batting experience and I'm always delighted to see the number of actions in the game increasing.
Another easy one - career mode is more fleshed out in C22 but the new stuff hasn't been massively popular with the career mode players, and it still feels quite bare bones in a lot of ways. You get a voice acted coach and a little intro bit with dialogue options when you start in club cricket but he hasn't said a lot in my own game since then - though possibly there's more content but I missed it through shitty batting- beyond occasionally popping into the dressing room to tell us we're letting ourselves down. As a career mode player from DBC14 I'm happy to see BA put a bit of time into this mode but I can't really recommend it as a big selling point over DBC14 or 17.
