I just rooted the mobs (or switched to Ebony Bladed Swords for the root proc) and gave the group a heads up that's what I was doing so the warrior could get in close. Then, if root breaks, it's at least on me and not a caster. Most warriors were appreciative... only a few got all upset that I insinuated they "needed aggro help". I was doing it more to save myself, really. :P

i love the ranger paradox: need to get up on aggro list so i dont die and lose my body

How tall is this little ranger we need to help? Short people weird me out.
