Honor should require 2 from randoms if you lost
It requires 2 from premade to get a reward even if you win the game, but not for a loss. This allows players, at least in norms, to queue up with the intention of losing quickly for the chance someone will just click them at the honor screen. They could even pretend to be a good sport about it while intentionally losing the game.
If your team loses the game, it should take 2 honors to get a reward even from randomly matched allies. That way the system can't be abused that way.
