I am almost amazed when
...I log into a rotating game mode and see Sona enabled. For fuck's sake, Riot. She regularly reaches, like, 70% winrate an ARAM alone. A permanent game mode. URF turns her way the fuck up to 11, and on every other game mode she reaches cancerous levels.
Granted, SR is what's the onus of balance, and admittedly Sona is not overwhelming there, but map-specific nerfs have a precedence. Please, tone down Sona on non-SR maps.
