Thank you for your feedback, but note, that it's not always about the growth rate.
1.3?? I can get normal hero with 1.45 without hero archives etc. only diference is that santa has 3 intermediate skills... that's not big deal since you can get that in no time by training hero and there is intermediate skill inflation on auction.
Point of epics is that they are better then all normal heroes you can recruit... now you made exception to that rule.
Santa is living, breathing hero to many children in whole world including some players here, and you made him weakest among all epics!!!
We should get compensation for this emotional trauma!
