Okay maybe I just don't understand what is going on here but it's like half the mobs in RoS Overthere just ignore Merc Tanks. Sabretooths, Succulents particularly the Merc tank will taunt then after 1 round will swap back to whichever player has the most threat, threat meter is saying like 45% then bam I have all the aggro until merc taunts & its back to 45%. Player Tanks & Pet tanks seem to be managing just fine but I don't have either of thise in my 3 box set up so I am having to rely on a merc tank & getting wrecked by half the stuff in this zone. Definitely feels like Merc Tank aggro is bugged. I am level 107 as is Merc Tank at the moment.
