All in all a true letdown to most who spent the time and gold in building this long awaited 2nd melee class.
Shadow stepping/ hit-N-run is nice but recharges are rediculous and require 2 slots if you chose to not use your elite for shadow stepping.
Even with this method an assassin is easily damaged when hit.
I designed this build and it brought new life to my character who I was about to delete due to its stereo type in the public view.
I have used ithis build and slight variations of its sort to both stay alive for extended periods of time While still able to deal the fair share of dmg in PvE, RA, GvG and AB's.
Assassin/Monk
11+3+1 dagger mastery
6+2 Shadow arts
8+1 critical strike
10 protection
Equipment: Zelous Kriss daggers of enchanting +5energy
armor: 50/50 mix shrouded and night stalker
HP:420......

Energy: 35
Skills:
Life Sheath { Elite }
Critical Eye
Deaths charge
Shadows refuge
Desperate strike
Leaping mantis sting
Jungle strike
Twisting fang
To anti Touchies, Stance warriors or smiters replace desperate strike with wild strike and replacing twisting fang with death blossom is suggested.
With this build you become much less a burden to a monk in PvE, Can effectivly manage health with minimal energy consumption and if managed properly deal fair amount of dmg.
Not to mention making them think WTF when they have a fairly strong Sin just not taking dmg like it should.
This build is not an excuse to tank but is is a way to stay in long enough to cut thru 2-3 extra targets and not having to worry as much about being spiked.
Again please try the build before you shoot it down. lol
Flame on.
