Yeah, I must say that I too like you have trouble getting out of bronze III, I play in the brawls with the HE Index league but I've lost some interest in the game too and don't have a lot of time to give to learning how to get there.
I do take advantage of the other options for earning, SPS, voucher, and I rent all my gold gold cards or any I have 2 or more of.

Sorry to read that you lost a bit of interest, but I get it. Other priorities. But we can still use the earnings options to our benefits :)
thanks for the pizza!
Oh yes this is true. I do have several rentals, I take part in the brawls and I do go back a couple of times a week and try to play some battles. I'm in for the long haul so whatever I can accomplish to me is a plus.
