does kiting work?

[Aghis]

Hello

I am lvling my 2. Tank and usaly when i pull several groups, and i feel my healer can't keep up with healing me, despite my def CDs, i run in a big circle around him, to lower the dmg i get.

I feel like that saved me from several wipes untill now because not all the mobs where hitting me and thus the healer was able to heal me up.
Edit. Yes i do stop running around when he stabilizes me ;-)

A Mentor and healer just told me, that kiting does not work. That this game does not work this way - after he pulled me into all the mobs and killied us all.

Well i stoped arguing with him to not make myself ragequit for the first time.

So dear experienced Tanks - is the Mentor right and i was fooling myself, or is my kiting something that actualy works?
