It takes a very special kind of player base to break a game so fundamentally that developers have to rewrite the core rules of character selection. The notorious 'GOATS' meta in Overwatch consisted entirely of three tanks and three healers, creating a mathematically unkillable deathball of hitpoints and healing auras. Because this rendered the entire roster of flashy damage-dealing characters utterly useless in professional play, Blizzard was forced to strictly lock teams to a 2-2-2 role format forever.
