I am maybe thinking too much, but...
Riot, you have been nerfing gold efficiency on a lot of items on the PBE.
At the same time, you have been giving to junglers less gold but more experience, with the change of items and monsters.
Now, I see that people can now know how many gold they are worth.
Furthermore, I see that the gains of exeperience from killing someone higher level than you are buffed and gains from killing someone lesser level nerfed.
So, I was thinking : is that some kind of plan to weaken the early snowball of some champ and allow teams that are behind to come back more easily ?
