Sometimes you just cannot get a group, maybe you are in an odd outpost, or u just feel like questing at ood hours. Well Henchmen to the rescue, maybe? I know i've been annoyed at not being able to issue them a simple command like /wait and not have them attack until i ctr + click. Or here's a good one. Let see how many apprecaite this- I'm looking to cap an elite in Mineral Springs, no groups interested, few groups around in general, so i figure it's an easy enough task, i'll just grab some hench, get my skill and be done with it. Well, after clearing most of mineral springs and not finding my boss, i head back to an uncleared area, somewhere along the way, 2 of my hench got caught between a rock, going back and forth. I didn't realize they were not in my party untill I died and my active hench died. I click on them only to realize they are caught in some bizzare loop and will only go back and forth, the healer and little thom i think. Anyway, since they are not under any threat they won't die, and i have no way to kill them, like /suicide or somesuch.
As painful as it was, i hightailed it back to Granite very upset and angry, a good hour or so wasted over something stupid like that! Let see if we can't get anet to add in some useful hench commands, hell even in PUG PvE groups you sometimes need a hench or two, how usefull would commands be eh?
I really agree with the OP. I think it should be possible to give simple commands to the henchies. So Arenanet: Please include a command called "Don't steal my loot!!!"
