Honor Multiple People
With the old honor system, you were able to honor all other 9 players in the game but the only reward was a small icon next to your name which was rare to get. Now with this new system, you can only honor one person on your team. This is nice however, there are some games where I feel like I need to honor all of my team mates but I can't.
For example, this game: https://imgur.com/a/RpMI8
This match was a 4v5 as Vayne rage quitted. In the end however, we still won. Everyone played a huge part but I was only able to honor one team mate but I wished I was able to honor my entire team or even the enemy team for being good sportsmanship.
