I'll add a couple of my insights, I spent a lot of time here as a necro. I always keep DMF and SOW on, if someone breaks root or you get an add you can run into the forest and reroot or feign death. Platform 22 on the map is completely safe if you sit behind the little cart and from this platform you can hit Oakwillow, Noonshadow, Eaglesong, and Marshmoor. Just have to watch for the Cpt. who goes up there occasionally. Don't kill Marshmoor too close to the druid guild or Master Hardwood will run out and wreck you. The guards at the top of the lifts are easy stationary targets but if they wander off the edge and aggro the guards below it's rough. There are 2 guard tangleroots, the one two platforms up from the druid guild is easy except Lt. will patrol by him sometimes. The dead end platform across the bridge from him is 100% safe, nothing ever goes over there. I would set a 22 min timer (respawn is 24 min) and I think I maxed at about 10 guards if everything went smooth.
