To clarify my post. There needed to be a balance in the game, and pve'ers/lifeskillers are said bread and butter. Whether that be supplying the market with accessories, weapons, drop items for people to buy. Or lifeskillers to supply needed consumables. Without them, the economy suffers and so does supply and demand. 

After that, now factor in cash shop additions because most of these players love costumes and pets. These players were tired of PK players running around flagged up killing them with no way to defend themselves. They just wanted to enjoy one side of the game and people cried about not letting them play in peace. It's like kicking puppies and kittens, but staying away from the apex predators. Literally Hyenas of BDO. Eventually the exodus began, and players packed up and left.

You know where this happens in real life? Impoverished communities and third world countries.
