Gimme some tips about my pve build

Here is my build

Hp 535
Mana: 33
Precision: 12+1+2
Expertise 8+1
Wildness survival: 10+1


I keep precision on 15 to increase critical damage and enhance keen arrow damage.

Invocation of djin is used to deal fire condition and distract enemy but i can use savage shot instead.

Broad head arrow is painful against caster but i like also prepared shot. Playing gw:en i negate murakai to deal any damage (also ice elemental wurm and more).

Kindle arrow add some damage.
Poison signet and Screaming shot to deal some good degen

Can i use supreme precision rune to keep it to 15 and so increase expertise to 10? In that case life drop from 535 to 495? is worth it?

Give me same tips

I'll go for a defensive stance and maybe change kindles for when you get out of shiverpeaks/killing destroyers.also ill switch djinn for something else.maybe conjour frost+icy bow
