football is kind of stale/frustrating to watch sometimes when it's over defensive or the match is ruined by playing dirty.

it needs a few tweaks like:

- 5 substitutions per match (big teams have a lot of good players conflicting on the same position)

- 15 minutes suspensions for misconduct like pushing/shirt pulling that happens especially before a corner/freekick; protests; faking/diving (in addition to yellow/red cards ofc)

- no offside if both the sender and the receiver are between the center of the field and the penalty box:

would be easy to judge, since the 16m penalty box line is marked.

what's your take on this?
