For pve use dual wield and bow. Rapid strikes as spammable and keep up dots like rending slashes, noxious breath, venomous claw, scorched earth, poison injection. As for tanking make use of earthen heart passives with igneous shield. A lot of tanking set ups depend on your gear. Probably want to use hardened armor, puncture, inner fire, heroic slash, talons, chains. Harness magic or shuffle if running armor master. There's a lot you can do but most builds are similar.
