Subject: Yellow cards

This will be good option to clear the yeloow cards at the end of the season. What do you mean?

clearing cards without changing the game would require a compensation and a higher chance of getting cards, so I would say no

+1 Cards should be cleared in the end of the season.

No need, if you have 2 Balotellis in your team, your quota will be reached quickly

this doesn't happen even in real life.
But I would love to see that yellow cards are different for:
1) League games
2) Cup games
3) Champions League games

Now it is annoying as hell to get stupid yellow on wednesday not so important game to miss Champions league or important cup game match.
