The Eternal Grove *need henchway tips*

Kurzick Mission: The Eternal Grove

Is this mission henchable?
If yes, does anyone has any advice to offer?

So far I made it to the last 3 waves, then got owned by the 3 afflicted bosses that came along with it.

Thanks.

I did it with henchies, being a warrior. The important thing I noticed is killing the siege turtles as early as possible, ignoring the rangers accompanying them for now until they move in, which they will, but later. Killing bosses last was not an option for me (besides killing monks and ritualists first of course) as their damage is devastating to the whole team, nothing compared to any other Tyrian Boss. They way I see it is to take compromises as henchies won't split and thus prioritize groves, even when two are under attack. In general, change targets and groves quickly, don't insist on clearing out a spot in total. Henchies can do the job just fine. I got bonus and extra with their help.
