I’m aware that every class has its specific roles and is vital to the overall team comp.

But, in terms of straight unselfish plays and high impact rounds, a good controller can win entire rounds by themselves from straight utility (not literally).

Every agent and player can frag on rounds, everyone gets a gun. For some agents, it’s easier also.

But a good controller can hold off entire sight lines and protect sites, prevents pushes into site, vital for retakes, and selflessly play for their team.
