DRK/GNB gap closer cause enemies to run behind you

When submitting a bug report, please use the below template and thoroughly fill out the necessary information.

Date & Time: Since 7.0
Frequency: Every time you use Shadowstride or Trajectory
Class/Level: Dark Knight and Gunbreaker
Steps:
1. Find a pack of monsters in a dungeon
2. Use Shadowstride or Trajectory at max distance while they're not aggro'd to anything
3. Observe how enemies will run behind you, because they're moving toward where you were first instead of where you are.

4. Now try with a Warrior or Paladin
5. Use Onslaught or Intervene at max distance on the same pack
6. Observe how enemies will collapse toward you without first going to where you dashed from.

Attached is a one minute YouTube video where I replicate the issue with Dark Knight.
I then go in as Warrior and show how it should work.
