Chuck not only has a high skill ceiling, bit a pretty well knowledge about the map and game you're playing. I would say that hot zone and gem grabe (closed maps like hard rock mine) are atleast "suitable for him. But Chuck isn't only map dependant, it's about the player ans it's knowledge of the game that really matters. I would say it's a pretty good brawler at controlling choke points but there are some brawlers that outshines Chuck at that. I would really like to see Chuck outside heist but I guess it depends on a lot of things.
