Favoriting Legends
In the main lobby, you would be able to go to the "legends" section and favorite the legends you play the most. This way you would be able to let the game do "random favorite legends" when selecting your legend, similar to the cosmetic options. and if you favorite the legends and you accidentally don't select your legend and someone takes your currently selected legend then it will randomly pick from your "favorite legends" rather than picking some random legend that you may not want to play.
Example: I have wraith selected before I queue into a match, I step away to use the restroom. First pick takes wraith, and i am automatically selected Gibraltar, a legend that I am not familiar with nor do i like to play. Instead I have wraith, octane and lifeline "favorited." Before I queue i have wraith selected. A teammate takes wraith and I either get Lifeline or Octane as they are my favorite legends selected.
The attached image is what I got the favorite option inspiration from. As there is a "Random Favorite" button which will give you a randomly selected favorited skin. I want this to be an option for the legends themselves.
