Be aware of mesmer wardens who will shater your enchants. Use Guardian as a cover enchant. Watch out for warrior wardens that will KD you with None Shall Pass. Stay away from any Oni spawns unless you like DP. Lastly, carefuly use terrain to kill Skill Hungry Gaki. Their spirits that strip enchants will be your end.
Finally, warden mobs are tough when you have rangers and warrior. The constant KD from hammer warriors and the bleeding from Brambles will make you cry.
I've had much better luck soloing this area with a touch R/N. There is a great thread in this forum detailing the exploits of the R/N community. Read it!
