DOT versus Buff
Gravemaker’s DOT bypasses Wilbur’s defense buff and shared damage buff allowing you to take our Wilbur’s allies, or Wilbur themself!
5* version
The Devs outright say Wilbur is a test of his special and a 5* version, or multiple 5* versions, could be coming ( Tarlak and rumored HotM Ranvir are both 5* versions of 4* Wu Kong ).
Boldtusk was a red 5* for all intents and purposes until multiple nerfs made him a true 4*. That Wilbur has not been nerf shows a 5* Wilbur could happen at any time.

Was Wilbur an example of that? He’s almost a 5 in a 4*'s body.*
Yes, and Merlin as well. We wanted a hero who could possess another, is a good example of a skill that was potentially too powerful for a legendary. Event heroes are designed in batches and can allow more range, while with the HotM, which are all legendary and released one by one, we are a bit more cautious and they are a bit more safe designed. With the Challenge Event heroes, we are able to be a bit wilder. This is a big topic!
