The ratios have been a problem for a while now. I don't have any answers. I just don't bother hunting in the main cave or breeding anything special - haven't done either, I mean really "play the game", in years now. I just keep breeding my waters and growing my water army. Occasionally I'll grab a water if its right there on the main cave to help unblock it for others, and then I'll grab new releases. That's pretty much all my involvement in this game/site now.
Would love to go back to when hunting in the cave was enjoyable and meant something. Open to all ideas.
