A cool mesmer skill

I just thought of a cool mesmer skill that would be for once a real illusion magic and drive players mad.

Circle of haste - Echo - 15 energy 2 sec cast time 30 sec recharge time

This echo lasts for 1...3 seconds. If target foe moves within that time he is teleported back to his starting position when this echo ends and this echo is reapplied.

Basically it means that if you move within that time you get teleported back so you have to stand still for that time to be able to move again properly.

It is perfect for:

1) retreat from melees
2) keep an enemy within aoe area
3) drive those wammos mad!

EDIT:
i wasnt shure aobut it being an echo or not but i think it logically is as it reapplies itself every so often (wich is what an echo is) else id say taht yea, it should be a hex spell.
actually it is a shadow step, but i didnt want to say shadow step as it is an assassin thing.
im not shure about how long i should last but i think that 5 seconds would be way too much...

Echo? WTF! Do you have any idea what that is? No, it should be a Hex Spell!

_Zexion

so its like the reverse of shadow step (kinda). Zexion your right it should be a hex spell, but you could have been nicer about it. The skill would change the game signifently and would put a spin on pvp. But on the other not anet would not put that skill into the game for it would make the mesmer too powerful and remove the checks each class has on it. Good thought though, i would love to use that skill on monks

Assains have already this, and that is not an Echo, that is a Shadow Step, a teleportation.

Why don't you add new skills to the build a skill thread to keep the place clean?

Mithran, im not aware of an assassin skills that cuase the enemy to shadow step / teleport.

I agree this should be a hex, not an echo, personally an increased duration up to 5 would be good, especially if it was a hex then it could be easily removed.
