Best "assassin" style build? (not necessarily rogue)

[Tomice]

Hi! I find it very hard to decide which class to take, which is a good thing!

 

I imagine my main char to be scout for the group, annihilating small numbers of weaker foes alone from stealth (either by sniping them from range or going melee, whatever gets the job done). The focus is single target DPS from stealth.

 

But I don't wanna be useless in group fights. The intro battle against the pirates made it very clear that I don't wanna suck when a scripted battle places me unstealthed in the front line. I also don't wanna die every time I can't oneshot a more powerful foe.

 

So basically, I wan't to play a solo-capable assassin.

 

Any suggestions?

 

 

 

PS: I'm intentionally not posting any of the concepts I came up with, because I hope to hear of something I didn't find myself. Thanks!
