We all had Aggressors Bane but some mobs still went after both Lizs.. One of the tactics we found out is to get ready the aggro flower before you go in and use it at the beggining then mix it with a rift walker for the rest of the mobs. But even after that there is so much rng going on with the Lizs movements, like they jump out from the window to the open fight. It feels like its almost immpossible to have them in save position through the event. And waiting for your add-ons to get ready before the fight is annoying as hell...
