It’s the biggest bottle neck in the game… Now skills costing over 40k to level just 1 X that by 55+ Heroes X 4 and just wow…
I cannot Evolve my heroes, I have nearly 8000 Hero fragments sat doing nothing.
It needs a big rethink , not just q couple new events for Cash only.
Like, let me sell some of my items or something, I have 5k+ of certain green items which will never get used.
The gold for bucks trading is a pure rip off so that’s out the question 
Come on Devs…
