Last season you could have got tickets for most of the home games even if you were a City Fox member. That means that come the start of the season, if you had a membership last year, you will have priority over any newcomers this season. Therefore it should be fairly comfortable to get tickets for at least half the games.
If you didn't attend any games last season, for whatever reason (and it may be a good one) then you will likely miss out on a fair few games. However, no doubt there will be opportunities to go watch some home games and build up your points tally.
At the end of the day this is the fairest way for the majority of fans. Of course, if it doesn't apply to someone and gives them a disadvantage, that automatically makes the scheme unfair! The club have actually put some thought and effort into this and listened to the fans. If you didn't give any input into those sessions then it really is your own fault for not making your voice heard.
Bottom line, I am sure if you have a membership this season (2017/18) then you will get to see a fair amount of games. Fair enough if you are only bothered about Man U, Chelsea and the likes then you may be in for a tough one. If you just want to go to any game then I am sure opportunities will arise. Demand is currently outstripping supply and the club are tied down by that. Ground expansion sounds like the simple answer and I am sure that is mentioned regularly but it is not an easy business decision and equally hard to approve and get done.
