I remember a few years ago the thrall were nerfed because Funcom said they wanted it to be about the player’s character not the thralls. Well once again their own updates have tended that a miserable experience. With the latest combat update and the mechanics of how NPCs and thralls fight parts of the game have become completely unplayable. The Grey ones has always been a challenge and they is great. But now any follow is quickly overwhelmed and unable to to defend themselves and the grey ones are so OP now that no matter the setup of a players character the risk to rendering Audis not worth it. It only takes 2-3 hits and the player is dead, all while they cannot be interrupted, knocked down, or affected by any sort of status (bleed poison). These new combat mechanics need to. E updated or simply returned to what has worked for the last 10 years! One again Funcom forgot the old saying if it ain’t broke don’t fix it.
They Grey Ones are very dangerous. Try drawing their aggro, running or dodging past them, then blocking while your thrall(s) attack(s) them from behind. Should work.
Ranged attacks might also work - never tried that, personnally.
