I slew them, and I’m totally disappointed. There is nothing great in them. Drop is random, which is stupid. But the main problem is npc’s AI. In fact they have no AI. It’s so easy to kill them, and that is boring. They just stay on one place and use debuffes. That’s all. No real attacks, no movement, no danger. Ok, they change the place, but just to stay on new one, so static like on previous. If this game was created in last century, it will be normal, but it’s game from 2012! Great bosses must be fast, strong, deadly creatures, with great drop, not big, stupid, static mobs. There is much more fun, and danger, in killing ordinary boss, than great, which is ridiculous. Fix it, Arenanet.
