Apparently the healer henchies are also going on strike...
I was out with another assassin lastnight trying to get some quests done and we decided to grab the henchies. The healer was doing a semi-decent job healing everyone except us. Both of us were totally aware we weren't tanks, used teleporting, etc ... and it was like she just didn't care about our health.
I've been using recall on the monks and allies so I can get in and out when I start taking alot of hits and it seems to be working out fairly well! In most cases, as soon as I get back to the monk I'm healed and able to run right back in and start taking out another target.
As far as making the wammo a priority goes... if I had $1 for every time a wammo has caused the entire party to die because they rushed things and failed to understand that others don't run on adrenaline, I'd be pretty rich!

Even when the monk(s) stand there spamming their energy because it's too low to do anything, some like to just keep on dragging more in. Some will get so upset that the energy dependent players need a few seconds to regen that they will bail. Is that really the type of player you would make a priority over another? Don't get me wrong, there are alot of excellent warriors out there ... but each profession has their idiots. If you refuse to heal assassins because of them, you might as well refuse the other professions as well! (if you decide to go that route, please stay out of my parties or delete your monk all together - a dead assassin is useless, but so is a healer that doesn't heal)
*coughs* Anyway, assassin still a new profession... while some have started to get a grasp on it, some are taking a little longer. Refusing to heal or verbally assaulting them (seen it way too much recently) on a mission isn't going to help them become better.
*wanders off*
