Best Mob?
I like the Nightmare Court. With their interrupts, knockbacks and stuns they have some of the smartest AI in the game.
Also enjoy the Toxic Alliance, how some mobs can heal each other and you can stomp the downed ones. Adds more pvp-ish elements to the AI.
Veteran Karka. I love ‘em. Fights against them play out differently from other mobs, you have to pay attention to not die (when alone), and they don’t last so long that you’d get bored.
Dredge. Because boon stacking + blind immunity + constant dazzes + knockdowns + rampage of projectiles are awesome.
The Unseen Hunter in Brisban Wildlands was the most awesome enemy I’ve come across in this game. Took me completely by surprise when I first encountered it (Never really played the original Guild Wars, so I knew nothing about the Largos), and as I was still pretty new to the game it actually killed me. After the fight I was like “Whoah, what the hell was that?”, and just had to hunt it down again. Good times.
