I don't believe in being a freeloader if I play a game a lot, but I don't believe in putting lots of money into a "Free to Play" game. However, once I hit level 40 (too early, due to XP boosts), I started running into walls. 

With patience you can tunnel through walls, but the only attractive thing about this game is the regular payouts. It's like a slot machine that has a lot of small winning combinations. Then you get to a certain level and everything slows down and it's just grind, grind, grind and nothing but the same daily rewards.

 I think it would help a lot if they made higher-level chickens easier to obtain. Latest offer has a decent flock of 5-star chickens, but for $30? And it has a lot of other stuff for leveling up champs. I have a bunch of champs stuck at max, need to be ranked up. Can we buy high-level chickens alone for a decent price?
