I used to think this but slowly starting to think more and more that its less about the weapon for the map and more about adopting different play styles to fit the map. The only thing I wish is that I was able to switch weapons based on he pool of weapons in the lobby. If there was a message that prompted "you have just joined a room with 3 other splatterscopes, would you like to change your weapon?" I have won matches with 3 chargers or 3 rollers on my team but the lack of versatility has hindered the cohesiveness of my team who aren't used to taking on different roles with their weapon of choice and if I cannot carry them, then we usually lose.
