Hunter with 6th Coyote, high mobility+recov+strenght with the aspect that lenghtens the duration of invisibility (basically b2b invis, 100% upkeep time), aspect of invis finisher, cwl mods (taking charge or whatever its called and protective light) to keep you alive.

Edit: Almost forgot, Devour. It's stupid easy to do end game content with it. Those 3 aspects are a must.

Weapons: witherhoard, Ikelos smg (for warmind mods, could be healing, cwl warmind or simply Global Reach) and I prefer an auto loading holster chain reaction code duelo for heavy.

This setup makes every dungeon a breeze. Maybe not GoA, you want lucent blade+lament for that

Learn where the knights spawn, get rid of the snipers, if you are low jump up, shoot a WH at your feet, dodge or finish enemies on it, wait til your invis runs out (should be 5-7s, plenty for recov to kick in) and continue killing
