In hero-shooter games like Valorant and Marvel Rivals, team composition depends on a mixture of roles and characters. A support main usually helps the team through utility like flashes, recon, smokes, healing, site control, or defensive setups rather than being the primary player expected to kill.
A Duelist, by contrast, is an aggressive role built to take first contact, enter contested areas, create space, and win fights. Duelists are expected to seek early engagements and get high-value kills, which requires quick reflexes and reaction times.
