I have a warrior that I think I've got a good handle on, skillwise. But I've been neglecting my rogue.

Here's my level 16 rogue build:

Skills:
Shadow Piercer + #'s 2,3,4
Aimed Shot + #'s 1,2,3
SSS + #'s 3,4
Shadow Veil + #'s 1,3,4
No passives as yet.

Weapon: Lvl 14 Deceivers of Brutality (50.7 DPS, 9 Str, 17 Dex)
Helmet: Lvl 16 Winter Wonderland Hood of Savvy (19 Dex, 7 Int, 1.46% Dodge, 164 Armor)
Armor: Lvl 16 Winter Wonderland Vest of Security (10 Str, 19 Dex, 297 Armor)
Ring: Lvl 15 Onyx loop of Potency (15 Dex, 8 Int, 2.6 Damage)
Amulet: Lvl 15 Arcane Pendant of Potency (18 Str, 9 Int, 3.0 Damage)

Stats (unequipped):
Str: 42
Health: 809
Dex: 78
Bon Dmg: 139%
Dodge: 6.85%
Crit: 2.95%
Dmg: 4.6
Int: 10
Mana: 225
DPS: 5.5
Armor: 0

Pets:
Currently using lvl 16 Deary
Also have lvl 15 Barney and lvl 7 Carly
Also have Blight and Jahooty eggs

I have very little plt and probably won't buy much, if any, more.
I have about 2.7k gold.

I still feel very weak and get killed very easily when more than a couple goblins from the tombs mob me.

What suggestions for improvement do you have?
