A magic jump-back stanza would be different from both speed and any auras. It has benefits (no or a very short cooldown, maybe similar to taunt) and disadvantages (very high sap, possibly some stamina cost,direction not easy to control).
My point simply is: If we can add something to the game that provides a tactical alternative, then it makes things more interesting. If I exaggerate, I could ask why do we need magic and fight skilltrees, since both accomplish pretty much the same thing: Instead of various elemental spells I could simply use ranged weapons, instead of drain speels I can use a bleeding axe, etc. Of course this would make the game much more boring. Most of us will want both trees over time to have more variety.
So in the end my point is about variety, providing PvE and PvP players some more things to develop tactics on/strategies for while at the same time keeping things balanced.
