This game really needs to give away resources.
I know you value some resources really high, but this will keep free to play players out of the game, and end up with no one discussing the game comp and anything.
People want to play and test different comp with different hero. But without resources, f2p can't get enough hero, even payed players cant get enough resource to build and test different comps.
I know this game got a lot of stuff in tank, and a lot in potential, but no one will be able to get it and test it, and there's not that much patience for player these days, they will end up all quitting really soon.
