Guild Wars 2

I want to make my level 80 warrior a longbow/rifle user. I’ll play it in dungeons with friends.
Which stats should I use? condition damage? precision? power?
Any tips?

Thanks.

Bleed will be your main source of Condition damage, and Bleed has a really bad scaling with the stat Condition Damage. I’d go with Power/Precision/Crit damage (Berserker) OR Power/Precision/Toughness(Knight) and let the Bleed/Burning be a nice side-effect rather than the whole focus of your build.
