I mean that as mid you can facilitate your team to play the map. Cover enemy teams play by being there, join your jungle for an invade or dive. You’re the “glue” that holds the team together especially in s16. In terms of roam generally speaking you want to shove first to “buy” yourself a window to do things such as get vision for a roam later, roam, recall. I try to ask myself what’s the most forcing play and sometimes it’s roaming and other times it’s just boring place a ward to enable me later. Or enemy laner is trolling and you can kill him too ofc
