I got the same problems as described by chaosguard. Right now you have to fully rely on Lucky Level to get you pushed, as somehow i get a lot less gold then i did before. Level 300 was reachable for me, now i cant get to 250 without waiting for lucky level a long time...
Oh and one more thing,
There is small items in the battleground you can click for money. For the devs, you might wanna scale this option into lategame. Im still getting 2$ per click but defeating an enemy gives 2-3K$
