Taking some liberties of copying this from somewhere else:
If I wanted to feel "mage-like", would I wish a push-back aura or something, something that tried to keep mobs on range, roughly something with mp's mezz pet success. Funny is that it wouldn't influence PvP much since melee are the ones most resistant to root-like effects...Yes, think it should be in that kind of effect-group.
Might be hard to balance, but if uncertain, make a perk line to boost it as this would require less perk points in something else.
