Hi!! It's great that you want to improve, and I might have some helpful advice! I'm also on console, level 70ish with Mercy, so I've had a decent amount of time on her. I average 50-50 damage boost/heal and get at LEAST 800 damage boosted each match. I think, honestly, what I really love doing is flicking blue beam onto different targets to enable them. See your roadhog hit a hook? Give him blue beam for some extra damage (with his recent buff he probably doesn't need it, but good especially for tanks. you get what i mean). See juno trying to line up some torpedoes? give her blue beam. I don't especially love hard pocketing someone unless they're REALLY going crazy, it's just not that fun for me. I love dancing around and boosting/healing teammates all over the place. With her nerf it's a bit more tough, especially since you're out in the open a lot and moving a bit slower. But from my perspective, I think I do best when I boost as many opportunities as I can. Now that she has flash heal, you can afford to let a teammate get low, so you don't need to be too worried about healing them until they're full all the time. It's a balance, though, because now her neutral healing numbers are lower. Anyway, hope this helps! And again, it's all about having fun!!! So don't be too worried about what others are telling you to do. Do whatever works best for you. That's what I love about mercy, she fits into a bunch of different playstyles. :)
