For PvE,Dungeons and Raids, I have made a build for DPS and Supporter. I've gone with Ranger/ Bard/ Nightblade. The DPS part is with the Ranger (remember it's not soloing), it has VERY useful abilities that to decent or more damage such as Rain of Arrows, Trick Shot and also with the Blood Raptor. Obviously Bard is for the support and everybody appreciates a bard in the group all the time. And Nightblade is an optional 3rd option but I just like the buffs it provides.

I had a couple of points left over so I just added them to bard.
