This is gonna be an odd thing to say, given that you're asking for enjoyment, but i'd say the key is patience.
I don't know how many innings i've played vs AI in casual mode where the first 10 or so overs i'm scoring one or two an over, but by the time i hit 20/25 overs my overall score is run a ball. I just played on where i think even by 30 overs i was still only just over 3 an over but when the bowlers tired i made hay, scoring nearly 300 in a little over 50 overs.
Another thing i do (massive sad w--ker alert)... Make a story... Play with your favourite players and build something around that. I have hardly ever played with current gen teams (except career) - i much rather play with WSC teams, the SA rebel teams, try and avoid the "blackwash" against 1984 Windies, that sort of thing.
Right now i'm taking my "Barbarians" on a tour of Africa, I set up the tour calendar in the academy: playing a odi and 3 dayer against uganda, odi and t20 against namibia, triangular odi with zimbabwe and kenya, 3 match t20 and test series against zimbabwe and 4 dayer against kenya... So while i'm really wussing out and playing against shit teams while my bowling improves, in my head i'm telling a story about how i'm a billionaire cricket-loving philanphropist who has exhumed/cloned players like bart king, tom hayward and wilf rhodes and have taken them to show the colonials how to play the game.
