The ability to share gold.... with rules to make it fair.

Rule 1: Can't do it until X time has been reached in game (example: 25 min) Rule 2: Can toggle option from base store. Players can choose another player to receive the gold they make for the rest of the game. Rule 3: Once you choose that option you can not undo it. Your name is removed or grayed from that list, and you can not earn gold for the rest of the game.

I feel this solves a few problems. The 25 min wait means people can't abuse it. If you are playing support, then there is a chance that late game you could be helped by the adc you have been helping all game. If you had a bad start to a game or you're struggling your teammates can help you out. Kill stealing is less stressful, in that, at least if they get their full build faster then their extra gold at some point might get kicked your way. Creates an additional strategy and opportunity for friendlier games. Finally it gets everyone their builds fast late game and if everyone is around the same level and has their builds then it's a game of skill at that point. Not who has the most items.
