As the title say, the mission is impossible without a full human party.
The henchmen keep attacking the guardians.
The solution for this would be, like suggested many times before, an AI customisation for henchmen.
What do you think of this?

Bloodstone Fen Bonus impossible with henchmen

Only solution I found was to get your henchmen killed off by the 2 nearby bosses - then do the bonus and then rez them.

There is another solution, which worked for me. As the Guardians are static, they will not chase you. The solution is to just keep running! If you run far enough past them then the henchies won't attack - sometimes you'll be attacked anyway by a small group of scarabs, which helps to concentrate the henchies minds. There is enough space between the pairs of guardians to do what you need to do to complete bonus. Only thing to be careful of is missing the path running past the second pair of guardians. You need to run over the log bridge - if you don't and have to backtrack you run the risk of giving your henchies the opportunity to spoil things for you.
The Amazing Krandor
I did this mission with my necro/monk, Stefan, and Alesia only. I went with primarily protection skills, so as to keep Stefan alive (I think I took one or two damage spells as well, since Stefan can't kill jungle trolls on his own), with Alesia as a back-up healer. When we got to the guardians, I beefed up the protections on myself, figuring at worst, Stefan gets beat to death by the guardians (since he can't take both by himself, and Alesia won't stop if I don't) and I Rebirth him later; best case, he doesn't stop. Got through all the guardians that way, with no casualties and a completed bonus.

Sadly, this and many other mission bonuses are basically impossible to do due to shoddy henchman AI and our total inability to use even the simplest of commands: STAY and FOLLOW.
Just those two commands could enhance the solo game 10 times - I hate having to go through endless PuG horrors just to get something done when I could have done it in one go with henchmen I could tell to stay or follow. As it is, henchmen AI means too many of the mission bonuses are totally out of the realms of possibility due to bulldogging from the melee's.
The Wilds bonus is horrific because you simply cannot stop the melee henchmen rushing in and aggroing a crowd of centaurs too big for a henchman group to handle. Divinity Coast is impossible because you can't stop the henchmen attacking the unimportant groups while you're racing to the ones attacking the chosen. *le sigh*

I completed it the same way Baza did - kept on runing. I ran pust the first guardans to the spot where moss scarabs spawn. Three of the henchmen started to fight and then got killed by the guardians, and I was with Alesia and Durham (I think) only. At this point I was pretty sure I was screwed but as I never saw the 'bonus failed' message (I actually thought I must had missed it) I countinued to awaken the druids and actually got the bonus.
