A few honorable practices that aren't covered by the current Honor system.
I just thought I'd make a list of things I used to honor other players for that no longer fall into an honor category with the new system.
Peeling for allies when they're about to get caught.
Leashing kills to teammates who need them more.
General play making.
Taking objectives solo without costing fights or objectives by being absent.
Stealing objectives from the enemy team.
Being an honorable opponent.
Anything I'm missing?
