Since I'm mostly a career mode player I'll give my hopes for some new features in the next game. Other than obvious things like "fix stats" and "fix having to choose your lineup 5 times in a row for one match" (yes this happened to me) of course.
-Ability to change teams. Preferably with a system where you're offered money contracts at the start of each new season. The money doesn't have to have any effect on gameplay but it would be cool to decide if you're going to pick your favourite team, the one that would give you the best chance of winning, or just try to make the most cash. Maybe having a running counter of "money earned in career" just for fun.
-Fatigue/injury mechanic. I know some people wouldn't like this so probably allow people to turn it off and I also wouldn't want it to be so harsh you get injured all the time. But it would be a neat thing for me to have to manage your playing time a bit rather than just playing in every game in every league.
-Fielding "moments" where you have to drop in from simulating to take a catch/enact a run-out. Currently I avoid playing pure batsmen because that's half the match where you're basically watching the scoreboard as it simulates. I'd love to play a WK to take some screamers and enact some stumpings.
-Ability to hit the gym with our career points so we don't get completely gassed after bowling 5 overs.
-Skills/fitness degrade if you don't put points in them constantly, eg. a bowling all-rounder who focuses purely on his bowling for a few weeks will see his batting skills degrade or a star batsman who doesn't work on his fitness will become lazy and slow in the field
. Again not too harsh to start with but maybe later on in the career skills degrade faster to simulate an aging player losing their touch.
