Party Sync in Timeless Isle completely overtuned?

like elites in the island hit like a truck, even with a 5 man team we couldnt bring down a group of 3 elites, autoattacks or spells hit for like 1/4th of our HP. their health might be okay its just their damage is unbearable. my voidwalker that can tank mini bosses in the Maw just fine here dies in literally 5-6 seconds to any elite mob
