I wouldn't mind how specific each rule can be so much if we could export/import them.
It is SOOOOOO time consuming to create a set of rules.
Then, heaven forbid you ever want to change them (or even one of them). You have to decipher what each rule does before you know where to start because the rule name/description is not displayed anywhere.
These are the main reasons I have so few rules, plus how limited some of the options are (formations, K/P options, timeouts, sub players/positions in/out, hurry-up, slow-down, etc.).
I'd really love to have more rules, but it's not worth the time required at this point.
