As for the Rogue, dunno how you make it, but maybe it's because I didn't want to use any melee skill, or maybe I was too much of a noob, but I had lots of trouble when dealing with bosses and most enemies. I had to leave some battles 'cos they were impossible, to the point that I had broken the equipment and had to repair it often. The best strategy I found over time was using traps, like the Poison trap. When I give another chance and after some experience with the game, that opinion might change.
So here is how I made the build (note that there are much better builds out there):
I really liked the feel of the core skill Flurry. It is important to get its related aspect in the corresponding dungeon to make it a 360 dmg move.
I personally like the rythm of the combo points system: 3 basic skills, than the core skills for big amplified dmg.
I use puncture as my basic skill, as its specialization allows to make enemies vulnerable. It in itself does respectable damage it seems to me.
I use one of the imbuements, still not sure what is best: for general play, I like the shadow one as it blows up the small mops. However, shadow is bad for single target bosses (see below how I fixed this). Here, the poison imbuement seems quite good - but I got tired swaping stuff for bosses, after trying it once. So I typically use shadow. Cold is also interesting - but I need more testing.
So my typically gameplay is to run around 3 basic skills, then the Flurry nuke. Poison trap is also good. The ultmate death trap is also quite cool. Not sure, which one is best. But due to having fun while playing I most often use the movement skils, dash and the other one that teleports you to an enemy - quite some style going on there
Problem is for single boss targets, it works, but is a bit slow. And the longer the fight, the more damage. For damage mitigation, I sometimes use the dark shrouds stuff, the circles around you - I am still not sure if this is good or not, but looks cool.
For single target: I am a huge fan of the Barrage animation. It looks great to me and I wanted to use it. In itself, for general play, it seems ok-ish to me. The single target dmg can be quite good, but only when you are super close. This was too cumbersome for me to maintain.
So the alternative that I started to use and I am happy with now is rapid fire. The animation is boring and lame, but it is very easy to use against big boss targets, you can also use it from the distance and hit all arrows. This has great single target dmg and I only use it for bosses.
I wonder if it is possible to make a build that includes FLurry + shadow imbuement for general clear and on top rapid fire with poison imbuement for melting single targets.
In conclusion, Flurry (melee) for general play; Rapid fire (range) for single target bosses. The rest of the skills I am still trying out what works best etc.
I used a Sigil to complete my first Nightmare dungeon and the quest appears highlighted like a main quest, but I don't know to which dungeon I should go.
