R/* rate my build

i'm trying to make a good trapper whit a bow for PvE.
the problem is that i don't know how to deal whit my attributes but this is what i think about it:

Wilderness survival: 12(+X)
Marksmanship: 12(+X)
The rest in expertise(+X)

skill's:

Barbed Trap
Dust Trap
Flame Trap
Spike Trap (Elite)
Troll Unguent

i'm still not sure about the attacks but this is what i chose:

Penetrating Attack
Power Shot
Read the Wind

please tell me what you think.

For a maxed out character that would be 12+/12+/3+ for expertise, which is too low and won't reduce your skills much.

Just look around this board for trapper builds and concepts.

I'd drop marks completely if you're gonna go trapping. If you wanted bow attacks use Point Blank shot. And since this is a PvE thing, I assume you want to be able to do this in combat? So you'll need something to dodge attacks so your traps aren't interrupted. So I'd Pick up whirling defense. You might also want to consider dropping Spike trap and picking up Oath shot. You'll be laying down more traps that way. Mantra of Resolve is a good skill to look into as well.

Well try this;

11+3=14 Expertise
11+1+1=13 Marksmanship
10+1=11 Wildy Survival

Dust Trap
Flame Trap
Whirling Defense
Penetrating Attack
Oath Shot [E]
Troll Unguent
Point-Blank Shot
Rez Signet

id keep what you have just more atts into your traps and also get a skill that you can cripple with so when u aggro u cripple and then run and trap and you should have a easy time

yea spiked trap isnt that great of a trap IMO since it does basically the same thing as barbed trap, and takes up an elite slot.
if u wanna use a bow too then use Barrage or Oath shot
also id put Serpants Quickness in there to use after laying ur traps

i just found a good bow of 8 markman req sow i was thinking about this:
mark:7+1
wild:12
expertise: just all that's left

skills:
Dust Trap
Flame Trap
Barbed Trap
Whirling Defense/Serpants Quickness
Penetrating Attack
Oath Shot [E]/Barrage [E]
Troll Unguent
Rez skill

thanks for all your help! but you think i can do FOW and UW whit this build?
