Does hammer beat assassinations or is it just desync?

I did a grappleshot into a room, I rubberbanded behind the dude like I usually do when I assassinate from above via grappleshot. And I melee his back, BUUUUUT He survives and I die.

If you’re desync’d it means the server probably rubberbanded you back to somewhere infront of your enemy meaning you just melee’d thin air and he clobbered you with the hammer.

Desync is such a pain I swear.
