Mercy’s home town. Would be cool to fight in front of the beautiful landscape. Something like the St. Pierre cathedral, The huge fountain of Jet d’Eau, or the Flower clock of Geneva.
Or even more grassy areas would be cool, and what better place than the gorgeous Rhine falls or mountainous Grindelwald? Overall this game could use more greenery, and perhaps even more mercy lore. And ofcourse, you could never have too many mountains
