Q u o t e: If you like monsters while pvping (wich i liked aswell in d2 sometimes, we did a few duels in CS without cleaning just to laugh at the guy who died by a monster) we'd need a open world imo.
But since we wont have the decision to do what we want to in 1 single world like at d2 (cause of the area story) there will be only 1. Pve and 2. pvp in area. And the arena is something like the cleaned bloodmoor from d2 for me, must be clean without any nuisance object to stay focused on pvp. It's a absolutely nogo to put monsters in that place.
That sounds boring.
Did you watch the PvP gameplay video? Think of that and throw in some Unburied. Or four King Leorics :-D
