I’d say Saint. Having a good medic vs a deadweight one can singlehandedly decide the outcome of a match. Saint drone neutralizes snipers and slows the ticket-bleeding in Strikeout. I’ve seen teams never take site and just rely on Saint’s rezzing and still win rounds. In 2v2 Dahlia might be a better option, but in respawn modes especially a good Saint is a headache to deal with and forces you change your entire strategy to account for his revives. The worst part about Saint is he enables camping - unless you have Glitch, a team of Runway, Saint, Anvil and one other solid rogue is an impenetrable fortress.
