I have a few clips from match #26325820 where there was some weird behavior that seemed like desync even though my latency was fine and server CPU wasn't too high.
1. Wraith and I teleport/rubberband at the end of my heavy melee, causing it to miss.
2. Shiv's heavy melee ends 2-3 meters from the bottom of the guardian stairs and hits me at the top. He hits me again with Slice and Dice which ends about 5 meters away from me, and then kills me with another Slice and Dice both during his heavy melee animation and after my charge goes through him.
3. I was here when the Puddle Punch went off:
It was aimed close to the middle of the ramp, while I was already halfway across the street:
4. Shiv heavy-melees the side of the bridge support pillar and hits me about 3/4 of the way to the other side. His second heavy melee animation completes before he rubberbands back in front of me because of my charge.
5. Shiv's second heavy melee on me goes through my parry. His fourth heavy melee misses me when it should have hit.
