GPM on new HUD

Ok so I was checking out the new HUD and thinking about what could make it better. I think a great thing would be to see you GPM. I'm not sure what the downside of this would be, but the positives are as new players you don't really see what impact your farm has on the game, and i think by showing this it could help them realize the importance of farming. Also if you are a player trying to learn a new champion this help you understand at what times you are what you need to stay on top of the game. It doesn't even have to be on the HUD you can put it somewhere in the shop. We don't have to see any beside you own but I think this could be a great thing for people trying to become better players. I don't know any downside but I'm sure there are some.
