I'm up and running, and noticed the same thing when I tried the game 6 months ago. Where are all the monsters? I flew all over, landed where I remember mobs used to spawn, and saw either 0 monsters or 1 monster in a large area and that's all. Also, they don't appear right away. It's like the game has to first figure out I'm there, and then after 5-10 minutes, a monster *might* show up.
I can see all of the npcs though. I'm playing on Blight, if that matters.
Also, my map will not appear. All I get is a spinning icon to show that it's loading (I guess) but no map ever appears.
I've waited a very long time to play again, and the game just seems horribly broken. Even on my super fast rig, npcs, terrain and other stuff take so long to "fill in" to areas I visit. I don't remember it being this way a year ago. Without a map and mobs to fight, the game it unplayable to me.
