In the future might you consider telling players who it was that honored them? Considering we don't see the Honor notification till we leave the post game lobby, it's not like I'd see "Oh, summoner X honored me, let me return the favor". I feel like the Honor system could help make new gaming friendships if it told you who was honoring you, because generally if they're going to honor you, it meant they enjoyed playing with you for whatever reason. Seeing this info might spur me to send a friend request.
I really respect you and your team so I'm sure this was discussed already. Might it be something you'll do in the future, and if not, could you share the reasons against implementing it?
