Which is why I said way earlier that "unless the tank is literally pulling to the wall". But most times there's no point to do that, not even to make sure the DPS aren't pre-positioned in front of you, because it doesn't really matter.
As to network delay, well, there's nothing to prove that I'm showing up in front or behind. But that's not the point. The point is, unless the tank literally pulls to the wall, it's often trivial for me to be half a screen ahead, meaning so far ahead network delay isn't going to make a difference, and I do the zigzag to put me back behind the tank.
But even that is not the point. As I said, the point is, use Arm's Length. Arguing about "oh no you can't out run tanks" or "tanks who get outrun by DPS are just bad tanks" or all that is all moot. Just use Arm's Length if you have it and find yourself pulling instead of the tank, that's what this thread is about.
