Any suggestions for rubber banding

Normally, I try not to move much because of this. But I'm playing a fast moving, whirling blades character, and there's so much rubber banding. It's not exclusive with this skill, it's any skill that moves you far quickly, like multiple flame dashes, or frostblink of the thing that lets you spam it.

Any suggestions on how to deal with this? Are there network settings or something? I'm getting in my 90s and it's the main source of death.

Make sure that you have Lockstep selected in Options > Game tab. If you already have Lockstep selected, then it might be worth running a WinMTR trace:

When did you last power-cycle your modem/router? Sometimes just doing that can solve a lot of issues.

Try DX12, I also ran packcheck and cycled my router over the weekend and it helped a lot.
