I've been trying to complete the Boreas Seabed mission with just henchies (yeah, yet another assassin who is banned from real PUG's). In this particular mission, they can be very annoying based on their rezzing preferences. Say I die and about 4 henchies including ritualist henchmen live. The rit. will prefer to rez the healer first over everyone else, no matter where the healer might have died (in this case the healer's always on the frontline, go figure

). The rit. will cast shelter KNOWING that it's going to be taking damage then goes ahead and uses flesh of my flesh. By the time the spell has been cast, the ritualist has about 25% health, then gets it halfed due to the spell. Both the healer and the rit die due to this, which is very retarded imo.
By the way, did I mention that on that particular time, I was the closest person to rez for the ritualist, and had rebirth? LOL. Great job Anet.
@ Ventius, I agree. They did in fact try to update the healer's use of skills, but I think they're just making it so difficult to use henchmen so we form real groups more often. If we're going to be forced into using only a single healer and no protection hench, then by all means give that hench Word of Healing at least!
