How do you get better at projectile and hitscan shots at the same time?

Hi everyone!

I main Ana and I always use VAXTA to practice/warm up my aim, especially mid-long range quick scoping and ADS shots. I think the practicing has paid off, at least to the point where I can pretty comfortably hit three clean shots on an unassuming Pharah (granted I'm silver rank so the flyers usually don't use cover).

Recently though, I've been working on my close-range hipfire shots with a different custom game. While this has made me more confident when dealing with flankers, I am now abysmal at landing my ADS hitscans shots. I can't hit any more flyers, better yet a midrange Cassidy who hasn't noticed me.

I just feel like practicing either shooting style makes me worse at the other, even though I still use VAXTA to practice my ADS aiming everyday...

And the weird thing is, this doesn't happen when I'm healing my teammates; I can land ADS, qs, and hipfires at the same level of consistency as before. So maybe it's a mental problem of having to switch between projectile/hitscan aiming while under the pressure of needing to secure kills?

Has anyone experienced something similar? If so, how did you deal with it? Is it something that gets better over time?
