Based on previous discourse about the card system I think that you’ll generally see a tendency towards blue cards in the first half when a red card might have been given before. Referees have expressed a reluctance to show red early in the game, because an early red can seriously change the game in a way a late red doesn’t.

I think the blue cards will give referees more freedom to enforce the rules without completely changing the dynamic of the game, and as long as you don’t actually believe the refs are conspiratorially disadvantaging any teams then this is a good thing.
