Paragon had some similar to the Fortnite (the original PVE version) problem. There was a ton of good ideas and components in there, but a lot of them were buried and took some time for a user to find and understand.
While MOBAs are out of favor now, I think there’s a lot of good ideas and characters that can be utilized for something really great. The deck-building system was so cool once I really started digging deep into it and understanding how it could affect different characters.
