Cheesing Raid trash mobs?

[Legidias]

Is this any different than using said pathing to escape from mobs? Lowbies in MM, if they get too much stuff, can run up the little ledge near zone out so that mobs go up that then circle back around so the player can escape safely.

Or in sol a, you can hop through the window near LS zone out and mobs will run the regular route.
