In general, what (Non-Duelist) agent is the most useful for a team to have that doesn't require line ups to reach their full potential? Lines ups are of course not required, but it is a part of using their utility to its fullest.

Played Csgo before and I was pretty alright, reached master guardian 1 or 2. Now here I am playing Valorant and so far all I’ve played is Kay/o, he has a flash, molly, and his suppression is amazing, shut down all utility and allows my boom...
