1. Use this spec:
http://db.vanillagaming.org/?talent#IVzbZbxAzRxotZxx0k2. Level engineering and make: Iron Granades, Gnomish Net-o-Matic Projector,Gnomish Shrink Ray.
3. Have gear with decent amount of stamina and shadow dmg.
4. Summon Voidwalker.
5. When rogue opens on you, he wont be able to kill you in stunlock due to 40% physical absorb from Soul Link and Master Demonolgost. After his opener, use iron granade and fear him during granade stun. After he trinkets/wotf, use deathcoil. He will be feared again for short duration, cast shadowburng>corruption>agony and recast fear. Cast shadow bolt, immolate and if he breaks fear, recast fear again. Use net if he manages to get close or shrink ray when he vanishes and gets into melee.
6. You always have healthstone and void sac to boost your defences while rogue has nothing to help against dots and will slowly die.
