Here's a parse of Evito doing 2509 DPS and my Guardian holding aggro. My guard at this stage had only the blue sword from Ardashir Fort, the quest shield from T2 (which is worse than the T1 guard shield), and a mix of khitai armour. Hell I didn't even have battlement legs at that stage, I still was wearing the wolf plate legs with no crit and no hate.
In case you are not familiar with this fight it is a straight up burn with some minor AOE damage around him and the tank gets knocked back during certain phases (and still held through the knock backs).
