I have compared other theatrics, rage and war glads gold income from the same level for wins. (It's hard to get all 3 to lose at the same time or within 3 just to see what happens for loses) But I've noticed a 27% increase in gold income at lvl 9 of crowd pleaser at lvl 10-17. Therefor I came to the conclusion every Level in crowd pleaser you get about 3% extra gold, no increase in tavern. Also I belive it effects arena challenges and you get a boost of gold there as well. Although it doesn't look that much from the %'s, this ONE glad can keep me wealthy in gold and can easily take care of 4 glads by himself at any lvl. I'm sure if I keep him long enough I will me rolling in gold. Hope this helped Thanks for Reading and good luck!
