Hello, silver dps here looking to improve, but mainly I need advice/tips on my dps pool(unfortunately its my weakest role due to weakness at playing hitscans(aim issues that I'm still trying to work on)

Though outside of aim, general positioning and ult usage is what I believe I need to work on.

But generally, I'm trying to be a better dps so I can be more well rounded as a player(gold tank, Plat support), though lately I'm trying to adapt to my aim weaknesses by playing generally less aim reliant dps heroes for my main pool, which is the following:

Junk(a bit rusty, but can pop off, though needs work on ulting)

Reaper(my overwatch 1 go-to dps, but the influx pof hanzos and widow have made playing him nigh impossible)(also Pharmacy is the bane of my existence when I'm on dps)

Bastion(dabble a bit, but aim issue here and positioning, mostly served as my pharah counter)

Sombra: my other main dps from overwatch 1, and the only hitscan I can be relatively consistent as, however, I do have the weakness of ending up "panicking" when getting focused, making me teleport back earlier than I would like, often leading to many missed support kills

Sym Mei(Mainly these 2 I pick up when there's a sweaty Tracer harassing my supports, though Mei I'm still trying to improve with her icicles)

And lastly, a recent pick up was Echo, solely cause I got sick of Pharahs dominating the match, I have been getting some decent plays with her, but as with all my other dps, using ult is probably the hardest issue I face with her, alongside aim improvement.(note, for her, I have jump binded to left trigger and grenades binded to A(xbox).

Last note: I do have 4 years on Widow, but have never been able to be consistent or truly effective as her, so I had to drop her going into overwatch 2(also my friend happens to be able to play a MUCH better widow than me, so I let him have Widow(helps cover my aim weaknesses when we're both dps))

Though I cannot provide any vods, I hope I can get some general tips for using these heroes more effectively, so I can be a better dps (And hopefully be able to overcome my "twitchy" nature that has lead to me panicking many times.

And thank you all in advance!
