What makes you enjoy playing MERCY?

I stopped playing Mercy in OW2. I’m not as in sync with her in 5v5 as i was in 6v6 so I main Kiriko now because she is actually fun a hero to play and I enjoy Kiriko’s pace in the 5v5 setting. If i go Mercy in OW2 it’s because there’s a masters hog or sojourn in my team and I hard pocket them for the free win. I have a 77% win rate with Mercy and i still refuse to even play her 90% of my games
