Lack of Gold
I dont know if it's only me but it feels like that every rank-up-material got adjusted well besides the amount of gold you get. If you rank up a champ (6*) from 0 to R4 it costs so much. I always got around 15 mil. gold. But with that much of rank-up-material given atm it shrinks so fast. I am at 7 mil. atm and the next R4 is possible in about 10 days.
Please give us more gold or a (not that time consuming) possibility to gain gold.
