I have done 2 levels in the Abyss now. It feels a lot like Dark Age of Camelot Frontier’s. The experience points are very good and you also gain Abyss Points which can be used to be gear. You also have the consistent fear of being ganked, which I have been a few times. Not every time I get attacked do I lose though. Sometimes I’m able to fight them off and kill them and other times I am able to run away.
I know I’m only 2 levels into the Abyss but so far it’s very fun. The risk versus reward is there to make me want to be in the Abyss regardless of wanting to PvP. The other nice factor is that if I get to frustrated there I can always head back to the normal PvE area’s where the chances of being ganked are MUCH smaller.
