Guild Wars 2

Hi guys.

I’d like some advices for my uncommon (?) build. I just love short bow.
Made few levels with S/P packing mobs spamming black powder but switched back to SB.

I’m level 32.
Using power/precision/mvmnt speed Signets to add some passive power (almost never use the actives).
Building toward Deadly Arts (III)/ Critical Strikes (I)/ Acrobatic (II) atm.

I pack 4/5+ melee mobs, run around em spamming Cluster Bomb while detonating it.
This way I can stack as high as 12 bleeds to all of them.
Signet of Malice provides a nice healing amount (3procs*20hp for each cluster*5mobs*5cluster=1500hp gained in 6-7seconds (hp pool being 2700))

As equipment I go for Power/Precision.

Here are the questions:
1) will it still be valuable as I level up?
2) what do you think of the overall damage output? (i don’t have much to compare with) besides mobs of my level fall quite fast.
3) precision/condition damage can be worth it?
4) what traits would you recommend to go with knowing how I fight?
I’m thinking of switching CS I for III (critchance on sides)

If you have any other suggestions, I’m listening.
Thanks ^^
