Can Rift Herald Give Global Gold.
I know it already gives like 50 gold to the team for killing it, but if it were to give 350-400 gold to each player on the team instead and make the buff work while you are with teammates, that might work at making bot lane less important. (I realize the snowballing issues this represents, but this is all I got at the moment.)
Edit: If you have other ideas, such as less gold or something else, please tell me, I'm open to ideas.
