From what I see is: You started twice a cast after his AoE. That way you are locked in a small cast delay on the server, it updates your position and then you have full wait time + lag untill it recognize that you are "beginning" to run! Try to wait untill your enemy moves before you start any cast. Thats not some sort of Netcode, but one of those things that adds delay, which makes the fight with higer lag pure frustration. Indeed SE have not done much yet to solve this problem, but let them do it step by step! To have now position updates each 0.1s instead of 0.3s helps a lot (also the other changes), but its not the only problem we had with "delay-stuck" previously in 2.0
