Pitch should behave realistically. Example - Ball pitching on the crack, Uneven bounce, amount of swing & spin as per the different stadium location. This all will be linked to dynamic weather conditions. Batsmen injury mechanics should be life like. Concussion on ball hitting the helmet, physio running to filed during injuries or cramps. Batsmen cramping while playing long innings, especially after hitting a ton. Most importantly whn ball hits the bat in C22, sound is not at all realistic. Fielding mechanics needs to improved drastically. Frequent dives to restrict runs, Fumble in the field while diving etc.
More suggestions from the community are welcome, cheers…!!
