I had the exact same problem.
I’ve been lowering my eDPI trying to find a break even point where I can both Rhein and DPS without having to adjust my muscle memory. I’m old. That memory takes longer to form every day.
Lowering my eDPI (its about…16,000 - 17,000, goal is 8-12k) over the weeks has been helping tremendously.
For me, this is what happens: My team makes space, I get good sight lines, and we squeak out a slight advantage which I can then exploit and snow ball. I crack head shots, and keep them pinned down/scattered. We win.
BUT…if the enemy BREAKS that space and gets in my face its even odds that I will get jittery and start missing shots. At my ranking I’m pretty sure its because of skill level of both me and everyone else. Not all enemies are created equally.
I was on Ashe yesterday. I’m not a spectacular Ashe, but I can hit enough Dynamite shots and lay down enough firepower to counter most bastion cheese that is common at my rankings. In the first round the enemy pulled a Dva to counter me. The Dva wasn’t particularly good, and I’ve been getting dived by Dva for ages now, so I know how to respond. I save coach gun and force her to burn her boosters and then reassert high ground. She has to retreat.
Enemy pulls a tracer. Harasses me and our Zen for days. I can’t make heads or tails of it, I can’t land any shots, and I can’t keep her off the Zen. It was miserable.
Fortunately we were in “snowball” mode, so I just kept dynamite on the payload and kept picking off the healers. The tracer didn’t actually get many kills, so swapped to deal with their stalled offense.
I think once I get my eDPI low enough, and my skill a bit higher, then those jitters will be gone.
This game is ridiculously complex. I really do love it. I just wish Blizz would let us fix some of our own issues rather than trying to make a perfect computer system.
Jayne’s tournament is a good example of that. “What would a ban system look like?” Well, at least now we’ve seen it.
