How about allow summoners to have the ability to see opponent progress in Battlegrounds? (Victory T)
Just thinking out loud as someone who would be nice enough to allow an opponent to win if he's just one stage away from the next level. This option will be entirely optional. You don't have to activate it if you don't want to see it (just like global chat).
Having this option would allow kind hearted summoners to give way to someone who is just one step from next level. Of course if both of you are on one stage away from winning then may the better player win.
