The last few days I have this issue. When I'm fighting any class other than scourge, I can drop a well, pop shroud and then death charge into my target. However, every scourge I have fought the last few days (lost count how many, >10 though), my death charge goes through the scourge, and i go flying past/through them without even hitting them once. I've only seen it occur against scourges. I assume its do to some syncing issue with a skill they are using, but i cannot figure it out. The scourge doesn't move erratically, nor pop their teleport, and are not in desert shroud.
I've fought warriors, thieves, regular necros, mesmers, eles, today, and never seen this issue. But with almost every scourge i've fought, i cannot land DC, and i go flying through them. Anyone else seen this?
