Guild Wars 2

I am currently using dagger/dagger and pistol/pistol but thinking on going sword/pistol and short bow because of the stun the sword/pistol has. As far as traits go I’m only level 68 and haven’t bought grandmaster yet sadly (wasted coin on crafting) so I have 20/5/0/20/10. My utilities are Hide in Shadows, Singet of Agility, Assassin’s Singet, Singet of Shadows and my elite is Dagger storm.

I think your utilities need to be more party based but definitely include Shadow Refuge because of the stealth and heal it can give to your teammates when they are in a bind or downed. And instead of 5 in crit strikes, I would put 5 more into Trickery for 3 more initiative so you can use your skills more.
