Season patches make last week's list archaeology
Marvel Rivals is balanced in fast, heavy swings, so any tier list has a shelf life measured in weeks. Team-up bonuses are the mechanic casual lists forget — a mid hero jumps a full tier when paired with the right partner (the whole point of the game). Role matters like every hero shooter: rank Vanguards, Duelists and Strategists separately, because a broken healer wins more games than a flashy DPS. And dive-vs-poke map identity swings placements hard. Date your list or accept that Season 1's S-tier is Season 3's bench.
