What genius decided to allow creatures to respawn while in an instance? It’s already bad enough that the “fight to survive” bar is always at about 35 – 40% when you die but then you make us battle our way through the sea of monsters just to get where were…only to die AGAIN and do the whole thing over, the game becomes nothing more than a huge grind of aggravation. This is the same nonsense you put into the GW1 Nightmare game when you enter the Vortex. It’s not a challenge. It’s just ridiculous, AI, nothing more.
I’m not asking for an effortless game, but I don’t want total impossibility either. You need to remove the respawn while in an instance. You also need to take a look at how death & survival are handled.
