Self-latent effects

[Blah]

With something like this implemented, I would intentionally aggro weak mobs for them to follow me, so that I could enjoy constant movement speed bonuses, even if I wasn't *really* fleeing. How would the game know?
That is precisely why self-latent effects, so one can do such things if/when they want. As for the other arguments when you're actually fighting, first you have to disengage then hit the macro or switch gears THEN hit the macro, all of which takes 4 or 5 seconds (or at least it seems to for me freaking disengage button) but with the effect just disengage and take off. And it could be argued that it could just be a constant effect, like actually just make all the Kupowers a constant effect....eh either way.
