To determine power creep you should compare an old version of a hero to a new version of a hero. You are comparing a basic, free hero to a unique, high powered, limited availability hero. These are two inherently different hero categories. There are many categories of heroes. As such, if you wish to prove power creep, you will have to do so step-by-step.
The first Challenge Event was Pirates of Corellia. With it was released Cabin Boy Peters - a respected 4* hero, along with Lady Locke who is considered the best 5* of the event. The most recent Challenge Event created was Santa’s Challenge in which Buddy and Mother North were released.
Comparing the stats and specials of Cabin Boy Peters with Buddy, along with Lady Locke vs Mother North, would be a start in establishing your claim.
You are also claiming that there is power creep in recent Heroes of the Month.
Comparing an apple to an orange (a Hero of the Month, rare, limited availability hero) with a basic TC20 hero (i.e. free and available permanently to all) is not a fair comparison. SG has already declared via showing us the Power number (Justice: 754, Kunchen: 770) that Kunchen is considered superior.
Has there been 5* power creep? Feel free to compare Season 1 TC20 heroes to Season 2 heroes… but pretending that a HotM is, or should be, equal in power to a Season 1 hero is being naive to how the system was created.
Here is a list of Heroes of the Month presented by the month of their release. It shows that Hel, Athena and Ares were the first three HotM relesed.
Here are the numbers of the first three HotM:
Hero |
Attack |
Defense |
Health |
Overall Power |
Hel |
745 |
692 |
1328 |
770 |
Athena |
737 |
692 |
1349 |
765 |
Ares |
777 |
659 |
1442 |
765 |
The three most recent:
Hero |

Kunchen |

Comparing HotM to basic heroes is absolute nonsense. The only way that such a comparison makes sense is if you wish to argue that SGG has organized the 3* / 4* / 5* or the S1 / S2 / Seasonal / Challenge / HotM hero categorization in a way that requires a rework. This, however, is a completely different discussion then, that has nothing to do with Power Creep.
Whether there exists Power Creep or not, I have no opinion on. I do not own enough 4* and 5* heroes to experience it and to have an opinion from my own personal experience… but to declare as such without using fair comparisons or citing source data is just not cool. Everyone should start from the same basic understanding of the facts at hand. Hopefully the above has helped lay a foundation for that mutual understanding.
