Back to soccer:
1.) Perfect: Game ejection, but no 10 vs 11 on red cards.
2.)
Unfair. See just the too many wrong given penalty kicks (either intentionally, or b/c the ref is blind). Exchange them with a free kick like in any other part of the field. Nice side effect: I guess diving goes down a signifant number.
3.) Just get rid of those passive/ non-passive offsides. Keep it simple. And
use technology for offsides. Since the linesmen simply can´t see it properly.
4.) Why? NASL tried game clocks. It worked almost* perfectly. (* They did make the mistake of going 90 mins real-time. They should have gone with 60).
Since game time is anyway around 55 minutes in nowadays matches (like this WC), make it 2x30. All stays almost the same, but no more time shaving and ref influence on game time.
Why not more goals? Just go back to 50s averages. It reduces ref influence, and gives higher variance (more comebacks)....
OFC basketball is ridicoulous. When you have 100 scores per game, you don´t need to watch the first 80...
Otherwise, I think you got my points pretty well.
