Me/Wa IW rogue in PvE?

Does anyone have experience with IW builds in late game PvE? I was able to get to level 11 pretty quickly with Me/Wa in the last BWE. For those levels I was able to use Distortion/Healing signet to keep me alive while using adreneline sword attacks for damage. However, I am curious about the post IW performance of this type of build in PvE using IW/Flurry (of course) and several tactics stances (like shield stance and bonetties defense). Can anyone comment?

For those interested, I really liked this build in PVP. For one, me/wa appears to be a really low profile build especially running around with a sword and shield. I dont think IW was disenchanted even once and was almost never "called" unless at least half of the rest of my team was already down. Moreover, it appeared to be really effective as a hit and run build: I was just shredding people to bits and by the time they noticed and started running, I'd cast my dots and they'd fall.

I used an IW build in PvE in the last 3 betas in all the missions past Lion's Arch. I loved using it. I used Ether Feast and Healing Signet to heal myself sometimes, but most of the time my healer was good enough.

The Storm Riders removed my enchantment alot so I learned to stack another one on top (can't remeber what I used).
