All melee classes on closed battlenet are completely useless due to this. You can have 91% hit rate and missing 50% of the time simply because you are not swinging where the enemy “actually” is.
I made an example video of this with my druid and at the end you can see what the problem is.
In single player this does not happen and the game is 10x easier simply because of how the networking is being done. Please learn from POE and use better networking methods so the game can actually be playable. Right now it’s just a nightmare to even want to deal with it. This has been a problem since 1.13 and still has not been fixed?!?!?!?!
