is my assassin any good?

well yah ive been playing phrophies for a while now and i just got factions a month ago and i havent been playing but now its summer and i started up again and ive made my assassin PvE and i think i made a pretty good PvE build and i wanted 2 know if its just me or is it actual any good....

1. Shadow Refuge
2. Way of Perfection
3. Critical Eye
4. Unsuspecting Strike (can be subed for anything which is lead)
5. Fox Fang
6. Twisting Fang
7. Death Blossom
8. Locust's Fury (Elite)

well stats are
Dagger Mastery: 13 have sup on
Shadow arts: 11 minor
crit strike: 12 Minor

well yah the thing is i havent died with this build at all with henchies or in a team now iam pretty far into the game.... well yah back to the main topic... is it just me or is this build good for pve..... and befor this build i had troll ugnent and apply posion instead of shadow refuge and way of perfection.. i didnt have that much healing but with apply posion and death blossom my enemys died alot faster.... so is it good or no

Personally, i'd drop the shadow arts just enough to raise the critical strikes to 13 for the extra point of energy on a critical strike. Your build isn't bad, but you have no get out of dodge skill, and with the fact that your running an enchantment on yourself, you could drop 4 and 5, put in Golden Phoenix (which doesn't require a lead, only that you be enchanted) and put something like disrupting stab in there also for those "I really need to interupt that heal" times This will drop your overall damage output by the 19 points that Fox Fangs adds, but you'll gain the ability to interrupt a foes actions.

but u see the damage out put i got here is a crap load every 5th hit is a dual basicaly and i get hella lot of healing by my self

I would try to get crit hits to 13. Youll get lots more energy that way.

I would also have a rez in there. :/

13 crit is not required in PvE IMO.

8 is just fine.
