actually you wrong. its much easier for shadow than for others coz all their attaks like toth's jumps switch and berserc , zorn's screams and debuffs all magic damage. if you are a good shadow tank you know when to pop resilience and u can absorb up to 20k dmg in 5 secs and cd on resilience average 45sec while other tanks will receive full dmg or will need to pop their abilities which have 2-3 mins cd.
