Yep, you read the title.
Developers should seriously use fan-made heroes.
There are AMAZING artists in the DB community that make heroes and too bad no one from the DB team notices their amazing work.
I'm looking at you @atKorosLit
The art has already been made for you, so has the abilities.
If the abilities seem a bit off, change them!
Like 80% of a new hero has already been made for you Boss Fight, now why won't you use their designs?
