Blazing Swamp, Pavel ruins and other places.
Full of bots, the worst sh** that I've seen on lineage 2.
I'm starting to think that NCSoft don't care about it.
That guys are farming adena to sell in external sites by real money.
For NCSoft is easy to eliminate the bots, the answer is inside of the game: Some areas has a good adena drop, but with none bots. Why?
However, the game still full of bots, that sh ** doesn't happen without being allowed, is not an hiding action. Even right now, if you login into game will see tons of bots.
