Ultron Boss in 5.4.6 needs immediate fix
His evade is bugged and this needs an immediate fix as it is going to kill a lot of people because of it. He only does a half evade and then strikes immediately. I did this last week with absolutely no issues with his evade as I know how to fight him. His evade bug does not allow for you to get out of striking range.
Given that this is already a difficult boss, we don’t need a game breaking bug like this on him. There is video evidence of this bug floating around.
