I'm too much of a chicken to try to gather up 4 of the lvl 65+ guys in fire and AE-kite them.
But... I've AE-kited with a druid a couple times at the 'Picnic Tables' in the 2nd castle in Fire, these guys are red but, I'm not sure what their lvl range is. The druid gathers up 4 and snares them all, HoS really makes this easier, and gets a nuke or two in. The bard just runs behind and plays AEdmg songs of any sort, you could also try to keep a few of the soldiers HoS'd. If you do happen to get aggro just be quick to fade and you're fine, otherwise a few hits and you're probably toast. :\
Alone, I'm not sure other than that you'd gather up a couple and just run around trying to stay within AEdmg range but outisde of their melee range... that and have a cleric handy because this seems like a death sentance to me.... I'm a huge chicken though. :D
