Hunting Area For A Level 50

Drauka

These places, give me dem.

Kyrra

I'm not overly fussed about keeping places secret, especially since you can slaughter basically anything in the game. Genji can be decent around the level 60-70 range, and can be done with manticores.

I hear Arcadia is pretty awesome for bashing as well. I wouldn't know first hand though.

People that explore will end up finding their own fave spots. Most just doing the same grind will likely do the same over hunted areas.

I consider myself lucky if I can get a clear of Dun Valley Barony, because I swear Darogan lives there permanently. :P

Averi

I circled manara from level 21 to level 78. I still circle manara sometimes. It's probably the best place for xp because you have very little chance of dying. 

Hyraeth

That's pretty much why I stick to Manara. Best bashing time for me is after I get back from work and am very tired. Low-risk works!

Xli

As a monk, Xli suffers from endurance drain, so Manara doesn't really offer good enough experience per mob. I try to bash the less bashed places. I would tell you where they are, but then they wouldn't be less bashed!

Nemutaur

Manara as people said and then upper Azdun Dungeon. When you feel tankier you can kill the Mingruk slaves in manara too, they're often better experience than the gnolls themselves.
