Has Riot mentioned what the precautions are for premades honoring premades?
With the new honor system, getting honor is going to be important for getting key fragments. But one thing that's been proven beyond a doubt in season 6 is that premades will blindly favor each other. If you want to get honor, it seems like it might be to your advantage to just play with friends if Riot doesn't do anything to stop premades from exclusively honoring each other.
It's most likely Riot has already thought of this. But I cannot find where they might have explained it. Does anybody know what Riot has said about this?
