ok, I thought of this a while ago, but never took the liberty of posting it, despite this, I still feel it needs polishing.

armour-amazly, you must run full enchanters, as there must be NO HESTIATIOn between attack chains
the build is quite simple, it utilizes fragilty with assasin condition attacks the damage is enourmous, entangling asp isure the target is knocked down and helpless, but as a result, you must make sure there is NO HESTATION between attacks, requiring that you use enchanters, for a energy boost. power drain is to quicken the "down time" after the chain is unleashed. I recommend you play this build with EXTREME caution, even though it should be able to take down any monk, including boon/prot, but you are EXTREMLY SQUISHY. phisical risitance helps if there are few ele, but every once in a while you encouter a elemental damage weapon warrior. right now, the obvious problem are the only in need of solving, aka, energy managemnt, self heal, "squishyness", but the actaull damage is insane, mos tmonk drop like flies, but only if you can be on full energy when engaging, as they'll be helpless to resist, and, almost certainly, die
question, skepticism and suggestion welcome

I suggest you remplace Physical Resistance by Distortion, you have 15 in Illusion and you use Zealous mod so why not.

I'm gonna unlock that elite then try this in AB and RA later. I'll edit this post with the results. 
EDIT: Ok. I've tried this build and the only problem I found was exactly what you pointed out, energy. I casted Fragility on the Monk and then hit him a few times to regen. I then unleashed te 4 attacks all in a row. By the time I was done, he was almost dead and had too many conditions to even begin thinking about anyone else. I love the damages and conditions. Power drain definately comes in handy when you're in a desperate situation. You have to be careful in Random/Team Arena because of your weakness when you die. It reduces your energy and really makes things hard.
Other than that, Francis' idea of replacing Physical with Distortion is very good. I can keep my energy level up while striking a foe and while being attacked by a Warrior.

If going illusion, you can max out your degen on someone, and then use the assassin skill Shameful Fear: Hex Spell. For 10 seconds, target foe moves 10% faster than normal. For each second, if that foe is moving, that foe takes 5...17 damage.

Haven't unlocked the Elite skill, but fiddled around using other condition-inducing attacks from assassin's dagger mastery
Tried this build in RA today,, was quite good, although i've been having problems with touch rangers... maybe because i dont have temple strike yet
but i dunno
Just one question though... wouldn't this be... uh... better... if it was a A/Me instead of Me/A..?

Frags got fubar after the nerf. Nothing fascinating about the skill anymore.
