bugged movements

Hey everyone I've been having an issue when fighting other players in game my character bugs out when he auto follows a target. I have played here for about a year and a half and have never had the issue before a few months ago. Its hard to explain what happens but when following a target my character will jump all over the screen and in some instances get so bugged that i cannot move at all. This is not lag i run around 34MS ping at all times in game and its become rather annoying to pvp with a melee character for me. Any ideas?

 

i think is bcs of anti speed hack system implemented^^

 

it makes pvp 10x harder on my melee character when i cant even move towards my target without having a mini seizure

 

Please record a video of it.
